Jupyter Notebook alt+D shortcut collision - ipython

I wanted to try out Jupyter notebooks, but quickly ran into problems with it since my keyboard layout uses alt+d and alt+f to insert ( and ) which doesn't work. All my other modifiers are also based on alt+{letter} and they all work, but for some reason alt+d and alt+f are getting swallowed by something. However I can't find any shortcut documented for those two combinations either.
I've added the following to ~/.ipython/profile_default/static/custom/custom.js
$([IPython.events]).on("app_initialized.NotebookApp", function () {
// No idea what these do, but the mess with my keyboard layout
IPython.keyboard_manager.command_shortcuts.remove_shortcut("Alt-d");
IPython.keyboard_manager.command_shortcuts.remove_shortcut("Alt-f");
});
But this doesn't seem to have any effect even after a server restart and browser reload.
Thanks

So after some amount of digging I figured out what causes this. The problem is not in the jupyter notebook, but is caused by a shortcut in the underlying CodeMirror editor. As seen here CodeMirror adds shortcuts for Alt +d and Alt + e. The way to disable these is putting the following in ~/.jupyter/custom/custom.js
delete CodeMirror.keyMap.emacsy["Alt-F"];
delete CodeMirror.keyMap.emacsy["Alt-D"];

VSCode autocomplete/intellisense(?) in Jupyter Notebook when starting string literals keeps making me accidentally insert 'ArithmeticError' every time

screenshot of the popup code suggestion box being mentioned
In VSCode Jupyter Notebook code cells, I keep having this annoying popup when I open any single or double quotes. It doesn't appear on markdown cells, nor in regular editor on .py files. It doesn't look like your typical IntelliSense suggestions either (I think), and I've tried to disable as many of such extensions as possible, but I'm not able to get rid of this annoying popup.
Appreciate if someone could point me in the right direction. Or at least what it's actually called, so I can Google the correct term. Thanks.
Figured it out.
In VS Code settings, go to Extensions > Jupyter > Python Completion Trigger Characters
defaults were: .%'"
So I deleted the single and double quotes, restarted, and voila, no more annoying popups.

VSCODE + Dart/Flutter: Double Autocomplete in conflict

i use visual studio code to create my flutter app, but since 1 month ago, i detected as if the editor have a double autocomplete.
When i write for example: "Container" i have the autocomplete while i'm writing, but if i press Enter it won't add the brackets at the end (before, it did!)
And, if i write: "child" i have the autocomplete while i'm writing, but if i press Enter, the cursor will be with a selection, and there is no autocomplete until i click in somewhere to remove the auto-selection, or i write the command completely without autocomplete.
It's like if there were a double autocomplete in conflict, that select the words after i press enter.
Autocomplete working:
Strange auto-selection and then no-autocomplete:
Furthermore, if i write "setState" and press Enter to autocomplete the function, i get the whole function selected and tabbed of 4 tabulation on the right. Same for initState.
I tried to disable every extension and restart, but i had same problem.
I'm so slow now to write flutter code, because i have to remember every CamelCase word and property and write them in every single char, or click in somewhere to make autocomplete works.
Fixed!
In setting i had to disable LSP.
"dart.previewLsp": false
I've the same issue, after some research I found this:
https://github.com/Dart-Code/Dart-Code/issues/2823#issuecomment-725630953
I'm not sure this is the right way because I didn't have try yet but the problem on GitHub issues seams the same you describe, apparently this solution works with LSP enabled

VSCode some shortcuts not working properly

latest version 1.40.1 on Windows 7 x64. I am developing in Java.
The most common shortcut, "go to definition" F12 and "auto fix" ctrl+dot
I tested it on another computer with 1.40.1. It works properly.
I have follow the key binding troubleshooting guide. When I record my key ctrl+dot.
It shows ctrl+oem_period. Looks like the OS is sending the correct keys to VSCode.
I couldn't find a way to reset VSCode key bindings and do not know what is actually causing this.
What should I do next? Completely reinstall everything is the last resort.
With the command Developer: Toggle Keyboard Shortcuts Troubleshooting, you can see which command is linked to a shortcut. It could happen that an extension is overriding the expected behaviour.
For example, I had an extension overriding the shortcut to reopen a closed tab, which didn't work anymore.
This resolves my issue:
Change your "keyboard.dispatch" to keyCode in the file settings.json
{
"keyboard.dispatch": "keyCode"
}
Your operating system keyboard shortcut is overriding the vscode shortcut. You should check your operating system shortcut key instead.
Just restarted the Visual Studio Code and the keys are working fine.
I was facing the same problem after I updated my Intel Graphics Command Center using Windows Updates.
The Add One Cursor Above/Below shortcuts were not working for me.
I started the Intel Graphics Command Center, and then went to System > Hotkeys tab, Enabled System Hotkeys as shown in the picture below.
I flipped my screen a couple of times using the keyboard shortcuts and then disabled once again.
Then switched back to VSCode and the keyboard shortcuts were working!!
In my case, "cmd+k cmd+0" which helps to fold all regions was not working.
Another extension was using the same shortcut. I followed the steps below to fix it.
Here are the steps to fix this
Press "cmd+shift+p" to open command palette
Type "Preferences: Open Keyboard Shortcuts" and hit enter
Press "option+cmd+k" to start recording keys.
Press the short cut keys that are not working (in my case "cmd+k cmd+0" ). This will list all the instances of that shortcut keys. And there are probably multiple instances of the same keybindings with some of them being used by an "Extension" as shown under the "Source" column.
Remove that and keep only that instance which says "Default" under "Source" column.
Now, you should able to use the default keyboard shortcuts.
Resolved :
Facing similar issue. Several keyboard shortcuts stop working when code starts running.
In my case it was happening because of notepad++ extension. Disabling that extension resolves the issue.
Sometimes this can happen because of change in environment variables. Please check if any recent program installations has made that change
You may also need to check the when clause of the Keybinding. In my case, I was struggling with why "Command+R" wasn't reloading the window on my Mac. By right-clicking on the row of the relevant command in Keyboard Shortcuts, then clicking "Change When Expression" and removing the expression completely, the keybinding now works as expected.

Try turning on Num Lock, it worked for me.
Extensions you add to VSCode also can override the ordinary behavior of shortcuts. I faced to this problem, I've noticed that the ordinary shortcut command + L which selects the whole line, does not work, and the reason was Live Server extension, which overrides that shortcut, after its deletion shortcut became work properly
I have tried many methods to solve this problem ,not every problem of mine got solved so I use this method after I cant find the solution.
you can first uninstall the VS code and then delete the .vscode file from C=>user=>admin=>.vscode
after that reinstall vscode ,from my end its working fine after doing this.
My issue is niche but never know, might help someone - YouTube Music Desktop player app was hijacking cmd, shift + l for me.
In my case, my Ctrl keys were mapped to the Toggle extension and this extension could not overwrite one of my settings in the settings.json because I had pending changes that hadn't been saved. Once I saved the file, I was able to use the toggle keyboard binding again. I used the guidance from Martin above to determine the cause of the issue.
99% works.
Forget everything that may overrides your keyboard shortcuts. The problems is your keybindings.json file, if you fix it you'll fix your problem.
I found the solution and I've explained it in the following link:
Why vscode shortcuts don't work properly?
Woo, found my issue was Razor Naga stuff. After I updated some of the Razor apps (it has Synapse, Cortex, etc), this issue started happening. Now, I saw these apps are running in the background although I am not using the devices at this time, and once I quit them, VSCode went back to normal thankfully.
In my case, I have installed some "vim keyboard extensions" and others. so I have uninstalled all the extensions related to the "keyboard" i.e. "vim keyboard extension" and now it is working fine. it is recommended to check if you have downloaded any extensions for the "keyboard" in the extensions and uninstall it. It might solve the issue.
This worked for me to fix CTRL+Space "Trigger Suggest". First I found and disabled this setting in: System Preferences > Keyboard > Shortcuts > Input Sources
Then I followed #ryandidevar's instructions and replaced everything for Mac: https://stackoverflow.com/a/72187880/14353462
Finally, I set "Trigger Suggest" in VSCode > Preferences > Keyboard Shortcuts to: CTRL+§ (which is right next to my "Z" key). CTRL+Space just would not be accepted under any circumstance. Now hitting CTRL+§ finally brings up the suggestions!
MacOS users,
This is a default macOS shortcut. VSCode is never getting the meta+shift+L message from your OS. Your OS is hijacking it. You need to disable it.

This is a default macOS shortcut, you can disable it at System Settings | Keyboard | Shortcuts | Services| Search with Google.

I just deleted folder in %APPDATA%\Code\ resets whole vs code and fixed my problem with alt + b and other vs code shorcuts not working
For me, It is the keyboard layout setting that causes this. Use English US keyboard setting.

Does VS Code has any shortcut like ctrl+q in eclipse?

Does VS Code (I currently use v1.8.1) has any shortcut like ctrl+q in eclipse?
It returns your cursor to the place where you stopped writing code(very useful for fast code browsing)
and it is different to alt+left which navigate backward
EDIT: I have found that this extension should do that you're asking. I suggest trying it out.
Original:
Out of the box in VS Code, this command does not exist. The list of default shortcuts can be found here, or you can open the keybindings settings in VS Code (ctrl+k, ctrl+s on Windows) and see which commands are available.
If you'd like to suggest this as a feature, you can open a new issue on GitHub or consider creating an extension.
If I understand correctly, you want a command that will move the cursor to where the last edit in a document was made.
This should be possible using an extension that listens to document change events and records the position of the cursor. Then, when the command is issued, it sets the editors cursor to that saved position.
You can also try "Eclipse Keymap" from Alphabot Security, has a lot of eclipse bindings.
I don't believe there is a built-in way to do this, but you could work around it by using an extension such as https://marketplace.visualstudio.com/items?itemName=alefragnani.Bookmarks .

Validate Autocomplete in Eclipse

Coming from Visual Studio and starting a project in Java, I realized I couldn't cope with having to press ctrl+space to have the autocomplete panel show up. An easy workaround was to set all keyboard characters to be trigger characters for autocompletion.
My only problem is that, when presented with autocomplete suggestions, a single press on the space bar will write the first proposition. In situations where I'm happy with the suggestions, that's just fine. In situations where I actually want to use what I wrote down initially, I have to press 'escape' first to remove the autocomplete panel before I can press 'space' safely.
Netbeans doesn't use the space bar as a validating key for autocompletion (only 'enter' does that) and I like that behavior. Any way to replicate it in Eclipse?
Thanks in advance for your answers!
EDIT: I should have mentioned I'm using Eclipse on the Mac.

I have the same problem with Eclipse Indigo on Windows XP actually. Coming from intellij idea, I also felt the need to set the whole keyboard to trigger auto-complete.
A quick proof that SPACE key does accept suggestions : type inte on a new line. If the auto-complete menu shows, press SPACE. It goes for Integer.
If anyone knows how to set the SPACE key to "ignore suggestions", it would be great, because the escape key on my keyboard is also too far away :)
Thanks
Edit : actually the best would be to have only the ENTER key validating, because ';' and '(' also seem to validate
I just tried to reproduce your behavior, but couldn't. Here is the configuration I have (and the steps I have done to reproduce):
I have installed Indigo (current version of Eclipse, version number 3.7).
I did not change any configuration there, this is what is the default:
Under Window > Preferences > Java > Editor > Content Assist, I have the following settings:
Completion inserts (instead of overwrite)
Insert single proposal automatically (which is ok most of the time)
not insert common prefix automatically
I have a simple class, go down to a method, and do the following steps:
Enter this.no and wait some time. Sometimes I have to press CTRL + SPACE, sometimes not.
Proposal pops up which includes notify and notifyAll.
I press SPACE and a space is inserted in the text, the autocomplete suggestions are closed without inserting anything.
I do not know if older versions of eclipse have the same behavior.
