I have an NKRO keyboard, so when I hold down a bunch of keys, sometimes when gaming, the "71 keys pressed in the last ____ seconds" window pops up from AHK. Is there a way that I can disable that window or remove it from the AHK program altogether?
AutoHotkey has two directives for controlling this behavior:
#MaxHotkeysPerInterval <Value>
This lets you define how many hotkeys can be fired within a certain interval (see below) before the warning dialog comes up. The default is 70.
#HotkeyInterval <Milliseconds>
This lets you define the length of the interval describe above in milliseconds. The default is 2000, which is 2 seconds.
This warning popup is in place to protect you, so don't overdo it with these directives. They are intended to prevent you from creating an infinite loop where a hotkey triggers itself. 70 hotkeys within 2 seconds is quite a lot for most applications.
Try adding #MaxHotkeysPerInterval 9999 to the top of your script. If that doesn't work, it might be useful to know what scripts are using in case those are contributing to the problem.

I want to map two dot/period key presses to Tab key in AutoHotkey script. I tried to map similarly as its shown for remapping semicolon key - on AutoHotkey forums, but it doesn't work. I tried following:
1. `..`::Tab
2. ..::Tab
AutoHotkey gives an error
.
I tried searching on AutoHotkey Remap docs, but couldn't figure it out. The period key is the one with the greater than mark and not the number keypad period key. See this: Dot/period key
Addition info/context in response to reply by user 0x464e:
Basically, I am trying to expand Emmet style abbreviations in devtools style sub-panel since the chrome devtools team wont implement it.
I am not a fast typist, so it's a pain to type complete property names. For example, if I want to type margin-top, (see the image), Chrome autocomplete brings up margin, margin-block margin-block-end etc.
Now, for margin-top, you need to at least type margin-t to get the autocomplete to show that property.
This is the case for many very common CSS properties like margins, paddings, etc., so autocomplete isn't great.
On the other hand, if I just type mt and have Autohotkey expand to margin-top, it's much much faster, saves me much time and keeps me sane.
Basically, I have setup some hotstring in .ahk script and they work too.
However, if I press mt followed by a Tab key press, Chrome's autocomplete takes over and hotstring fails, (try once to see the problem). Instead, currently I press spacebar, or . (period) to trigger the hotstring. It works, but the problem is it leaves a space or a dot with the expanded text. [see this].
So, that's the actual reason I wanted a double period key trigger to replace Tab.
It would be great if the hotstring trigger would work with a double period key, but doesn't leave the trigger character itself and then have send Tab so as to jump to the value input of the just expanded property.
You're not really looking for a traditional remap, which is why you didn't find it from the documentation.
Remapping is just simply remapping one key to another, but you're not trying to do that. You're trying to make some action do another action.
Anyway, what you're asking is doable, but there's loads of different ways it can be achieved with difficulties varying from simple to extremely advanced & complicated.
You'll need to specify things more clearly before this can be answered properly.
Biggest questions that pop into my head right away are at least:
Should this work everywhere, or just in text input fields?
How should the original functionality of . be preserved, if at all.
(What should happen after the initial . keypress?)
Should there be some timeout between the keypresses?
Etc, this is just what I could think of right away, but surely there's more.
Anyway, for now I can give a simple implementation with a hotstring:
:*?:..::{Tab}
So this is a hotstring with the * and ? options.
I'm guessing these would probably be pretty good options for this.
So what this does, is it presses backspace twice and sends a Tab if you type ...
This should be fine for text editors, but it leaves much to be desired (the points I listed above aren't considered since I can't know what you're looking for. This is just what a default simple hotstring can offer).
Looks to me like you don't actually want the additional mapping of .. to Tab, but instead just want to update your existing hotstrings to activate immediately (without waiting for an EndChar) when the hotstring is followed by ..
Normally, you might look to the Ending Characters option to create this functionality, but since you want multiple characters to trigger this, we need to look to other options.
I will be using the example of ::mt::margin-top for my sample implementation. Extend any changes I make to these to the rest of your hotstrings in the script you screenshotted.
Here are the changes I am making to this example:
Add your .. to the end of each of your hotstrings triggers. For example ::mt::margin-top becomes ::mt..::margin-top. However, at this present, this still requires some sort of ending character to be pressed in order to proc. Let's fix that in the next step
Add the Asterisk Modifier to the hotstring. From the docs:
* (asterisk): An ending character (e.g. Space, ., or Enter) is not required to trigger the hotstring.
Final code for ::mt::margin-top example:
:*:mt..::margin-top
And extend this * insertion and .. appendation to each of your hotstrings.
Hope this helped! Lmk if you need any more help or changes.
In my AutoHotKey script I'm using #IfWinActive to detect if the Roblox window is in focus, and then press the number 1 button whenever left clicking the mouse, like this:
#IfWinActive, Roblox
LButton::
MouseClick, Left
SendInput, {1}
return
#IfWinActive
It works great, except for when I'm clicking out of the Roblox window back to another window. It still fires this code on the first click, resulting in it typing the number 1 into Notepad (or whatever window I switch focus to).
I figured that when I'm clicking on Notepad the focus is still on the Roblox window, which is why the code still fires. So I tried changing the code to this:
#IfWinActive, Roblox
LButton::
Sleep, 100
if WinActive("Roblox")
{
MouseClick, Left
SendInput, {1}
}
return
#IfWinActive
Assuming that by the time the Sleep finished the focus would have shifted to the Notepad window and If WinActive("Roblox") would return false, but it still returns true and types 1 into Notepad.
I also tried using StartTimer and a label, thinking that maybe the Sleep wasn't asynchronous, but that has the same problem as well.
Anybody know how to get around this issue? Thanks in advance!
The main problem in this case is that the hotkey is fired immediately after LButton is pressed down and the Roblox window is still active.
The only solution I see is to fire the hotkey upon release of the LButton using the tilde prefix (~) to prevent AHK from blocking the key-down/up events:
#IfWinActive, Roblox
~LButton Up:: SendInput, 1
#IfWinActive
There are a couple of ways we can achieve this. TL;DR for solution, check the yellow part of this post.
Firstly I'll address the problems in your code:
Usage of MouseClick over Click. Technically nothing wrong, but Click is said to be more reliable in some situations and easier to use. Looks cleaner as well.
Wrapping 1 in {} is not needed and does nothing for you here. In some cases you may even produce unwanted behavior by doing this. In a send command, {} is used to escape keys that have special meaning, or to define keys that you can't just type in. More about this from the documentation.
Having a somewhat of a bad WinTitle that you're matching against. Again, nothing technically wrong, but right now you match any window that starts with the word Roblox. Shouldn't be too hard accidentally match the wrong window.
A quick and a very effective solution would be matching against the process name of your Roblox window.
So #IfWinActive, ahk_exe Roblox.exe or in an if-statement if (WinActive("ahk_exe Roblox.exe")) (assuming that's the process' name, I have no idea)
For an absolutely fool proof way could match against the hwnd of the Roblox window. However, that's maybe a bit overkill and you couldn't really use it with #IfWinActive either. An example I'll write below will use this that though.
However, problems 1 and 2 can be entirely avoided by doing this neat way of remapping a key (remapping is pretty much what you're doing here).
~LButton::1
Ok, so why does that work?
key::key is just the syntax to easily do a basic remap, and with ~ we specify that the hotkey isn't consumed when it fires.
Cool, but now onto the actual problem you're having.
So what went wrong with the sleeping thing? Well since you're consuming the hotkey, all you're actually doing is firing the hotkey, waiting 100ms, then checking if Roblox is active. Well yes, it will still be active since nothing was ever done to switch focus away from it.
If you were to not consume the left clicking action, it would work, but it's definitely not a good idea. You do not want to sleep inside a hotkey statement. AHK does not have true multithreading and unless you would've specified a higher #MaxThreadsPerHotkey for your hotkey, all subsequent presses of the hotkey would be totally ignored for that 100ms.
So yes, with specifying a higher amount of threads that can run for that hotkey, it would kind of make this solution work, but it's still bad practice. We can come up with something better.
With timers you can avoid sleeping in the hotkey statement. Sounds like you tried the timers already, but I can't be sure it went right since code wasn't provided so I'll go over it:
#IfWinActive, ahk_exe Roblox.exe
~LButton::SetTimer, OurTimersCallbackLabel, -100 ;-100 specifies that it runs ONCE after 100ms has passed
#IfWinActive
OurTimersCallbackLabel:
if (WinActive("ahk_exe Roblox.exe"))
SendInput, 1
return
And now onto the real solution, to which #user3419297 seems to have beat me to, just as I'm writing this line of text.
Using the up event of your LButton press as the hotkey.
#IfWinActive, ahk_exe Roblox.exe
~LButton Up::SendInput, 1
#IfWinActive
This way the down event has already switched focus of the window and our hotkey wont even fire.
Note that here we unfortunately can't use the key::key way of remapping I described above.
Bonus:
Here's something that could be used if the up event of our keypress wouldn't be desirable, or somehow the window switching of the active window was delayed.
RobloxHwnd := WinExist("ahk_exe Roblox.exe")
#If, RobloxUnderMouse()
~LButton::1
#If
RobloxUnderMouse()
{
global RobloxHwnd ;specify that we're using the variable defined outside of this function scope
;could've also ran the code to get Roblox's hwnd here every time, but that would be wasteful
MouseGetPos, , , HwndUnderMouse ;we don't need the first two parameters
return RobloxHwnd == HwndUnderMouse ;are they the same hwnd? (return true or false)
}
Here we're first storing the hwnd of our Roblox to the variable RobloxHwnd.
Note that Roblox would need to be running before we run this script, and if you restart robox, script would need to be restarted as well.
So adding some way of updating the value of this variable on the fly would be good, maybe under some hotkey.
Then by using #If we're evaluating an expression (in our case, running a function and evaluating its return value) every time we're about to attempt to fire the hotkey. If the expression evaluates to true, we fire the hotkey.
Usage of #If is actually not recommended, and it is good practice to avoid using if at all possible. However, you wont encounter any problems in a script this small, so using #If is going to be very convenient here.
If you were to have a bigger script in which there's a lot of code running often, you'd be likely to run into problems.
This question already has answers here:
Stop and continue execution from debugger possible?
(6 answers)
Closed 8 years ago.
Strg+C stops and kills a Matlab script (at least sometimes). But is there a way to stop a Matlab, take a look at some variables and continue the calculation?
I am not talking about just setting a breakpoint. I want my script, let’s say run for couple hours come back to it hit some buttons that stops the calculations take a look at some variable and then continue the calculation.
I tried to find out if there is some shortcut key for this – I am quite sure there isn’t.
Now I was thinking about including an if-case that looks if a certain button was pressed by the user. If so there would be a useless k=0 line and a breakpoint on it. And if no one is pressing this button the loop would continue. But this is where my limited Matlab knowledge leaves me. I don’t know if there is a way to ask for a user-button press but don’t wait for a button press like in the function input. Also I just have a running script, I don’t have any GUI.
To drop to the command prompt you need the command keyboard and then type return when you have finished (you don't need a breakpoint). The tricky bit is how to trigger it. There a few options. The easiest is to open a figure window. The following code halts the process when any key is pressed.
keyDownListener=#(src,event) keyboard;
fig = figure;
drawnow
set(fig,'KeyPressFcn',keyDownListener)
for p=1:10000
%do some thing
end
You can modify this to test for a specific key since the keypress is contained within the event struct.
To use no figure gui at all its more of a problem. I'm not aware of a non blocking keyboard input method. A mex file the runs kbhit() in C might do it, but kbhit() is not standard C so it would only work on Windows. An easier option maybe to test for the presence of a file.
for p=1:100000
if exist(fullfile(pwd,'halt.tmp'),'file')
keyboard
end
%do something here
end
This drops to the debug console when halt.tmp is created in the current directory.
Other potential methods could involve using multiple threads to read 'input' (either the Parallel computer toolbox or undocumented Java code), or using http://psychtoolbox.org/ as mentioned by #bdecaf
I have a simple question, although it's harder than it seems; I couldn't find the answer on the interwebs :O
I'm writing a script in Matlab. What I want to do is the following:
When I press the esc key, I want a helpdialogue to pop up, so my script pauses. (So when I press esc, I want to stop the whole script to run so that the car (which im writing the script for) stops driving)
How do I do this? How can I say to Matlab: When I press esc, do this...
Thanks for your time guys!
EDIT: It's no option to implement something which awaits the keypress. Im writing a script for a driving car. It just has to drive around basically, but when I press esc for example, it should stop driving. So the script just has to run, untill I press the esc key; then the script has to pause.
KeyPressFcn is good because it forces you to write event-driven code. Which is generally a good idea! However, if KeyPressFcn doesn't seem right for you, for example if you must keep running in a loop, and you just want to poll whether a key has been pressed, I found this solution buried in the matlab website:
get(gcf,'CurrentCharacter')
Then you could set this property to a blank, and poll it as required.
e.g:
finish=false;
set(gcf,'CurrentCharacter','#'); % set to a dummy character
while ~finish
% do things in loop...
% check for keys
k=get(gcf,'CurrentCharacter');
if k~='#' % has it changed from the dummy character?
set(gcf,'CurrentCharacter','#'); % reset the character
% now process the key as required
if k=='q', finish=true; end
end
end
This worked well for me in 2014b. The downside is that the graphics window needs to be focused to receive the key events.
In a matlab figure you can define a 'KeyPressFcn' that works similar to do what you ask.
If you are in the console you have to work around that matlab is single threaded. Basically you need to halt the program flow to check for key presses.
btw - also when you use 'KeyPressFcn' you will need to make some pauses so that Matlab will check if anything has happened.
btw2 - I should also add during this pauses Matlab will not only read your key presses - but also do some housekeeping such as redrawing its window and stuff.
I frequently ran into similar use cases and typically preferred to react to joystick buttons because of the more convenient interface provided by vrjoystick. However, I recently wrote a library that provides a similar interface for keyboard inputs.
% Pause on ESC
kb = HebiKeyboard();
while true
state = read(kb);
if state.ESC
% PAUSE DRIVING
else
% DRIVE CAR
end
end
It's non-blocking and doesn't require focus on any particular figure.

I had a related task once, and i did it with getkey form matlab file exchange.
Basicly you will want to have it listen for ascii 1B (27 decimal)
if getkey does not solve your problem you can still have a look at its code and maybe find the line that will do the trick for you.
I have written a python script for my co-workers, and then created an autohotkey script to run it every time someone presses Ctrl+LShift+Y. Looks something like this:
^+y::Run helper.py
The python script is fine, but the ahk script doesn't work on all the computers. Sometimes it works fine, and sometimes you get this error:
^+y does not exist in current keyboard layout
Now, searching the web this seems to be a problem with multi-language keyboards (we're using both Hebrew and English), because different languages means a different layouts (I guess?). I also found someone explaining that to solve this you need to use scan codes instead of the usual ^ and + and so on (I'd link to it but I cannot seem to find it now).
This all vaguely makes sense to me on a theoretical level, but when I want to realize it with actual code, I don't really know what to do. To me it seems as if this topic is hardly discussed (with the few exceptions being lacking in examples or hard to understand), so I'd love an answer that would include the following:
some simple way of determining the scan code for a key. This should preferably be a pythonic solution (and just out of curiosity, I'd love to know how to do this with linux as well). This is probably the easier part (but I think is an inherent part of a complete answer).
This is the important part: examples of how you implement that scan code in an autohotkey script, including edge-cases (if there are any).
Question 1
As you want to use the key with autohotkey, it makes sense to use autohotkey detect the key in the first place. Obviously this method works only on windows where autohotkey is running.
Write a Autohotkey script with this line and run it.
#InstallKeybdHook
Press the key you want to examine.
Open the script menu by right clicking the icon of the script in the right lower corner of your screen.
Select OPEN, then from the Menu "View / Key history and script info"
There is a line for each keypress.
First column is the VK (Virtual key) code, next is the scancode.
For example for CAPSLOCK the VK is 14 and the Scancode 03a
Question 2:
#InstallKeybdHook
VK14::
msgbox, you pressed capslock!
return
OR
#InstallKeybdHook
SC03a::
msgbox, you pressed capslock!
return
both work.
Note that you can combine two keys into a hotkey by combining them with & (but not 3)
#InstallKeybdHook
RShift & SC03a::
msgbox, you pressed Rshift capslock!
return
You can modify a Scancode with + and ^
#InstallKeybdHook
^+SC02C::
msgbox, you pressed Ctrl Shift and Y(maybe)!
return
Further info about this is on the page "List of Keys, Mouse Buttons, and Joystick Controls" of the autohotkey help file that comes with the default installation.
