Referring to the Texstudio user manual section 2.7.1 Manipulating tables there is the shortcut Ctrl+Alt+Shift to enter block selection mode.
Is there a way to exit that block selection mode (i.e. go back to only one cursor), using only the keyboard?
Unlike other editors, Esc does not work.

I am switching from PyCharm to VS Codium. I want to be able to disable breakpoints by middle mouse click, like in pycharm.
Currently, I can disable a breakpoint by right click at breakpoint and select Disable Breakpoint:
Another way is to disable it in list in Breakpoints view.
But I want to be able to quickly enable/disable it by just clicking with mouse wheel (middle button). Is it possible to configure VS Code this way? Currently, when I middle click on breakpoint, this is ignored, and instead a text from selection clipboard is pasted (it is the default behavior in linux). Visual Studio Code version is 1.66.1.
There is no way at the moment to customize mouse click events. There are a few hardcoded options you can change in the settings, but it is extremely limited like pressing ctrl and the mouse wheel for zoom. As far as I am aware, disabling breakpoints is not among those options.
Check out: https://github.com/microsoft/vscode/issues/3130
I currently use the following workaround.
Remap the middle click to some button.
For wayland several utilities can be used for that. Let's take kbct.
Add such config (edit for your needs)
/etc/kbct/config.yml:
- keyboards: [ "Logitech MX Master" ]
keymap:
btn_middle: f15
Then start kbct.service.
Create the ruler script
Make the file choose_press.sh:
#!/bin/bash
class=$(xdotool getactivewindow getwindowclassname)
if [ "x$class" == "xVSCodium" ]; then
ydotool click 0xC1 # right click
sleep 0.2
ydotool key 107:1 107:0 28:1 28:0 # End, Enter
else
ydotool click 0xC2 # middle click
fi
Do not forget to add executable permissions.
Bind shortcut to the script
To assign a command to shortcut in KDE, go to System Settings -> Shortcuts -> Custom Shortcuts, right click, choose New -> Global Shortcut -> Command/URL. Go to Action tab and fill in the command. In this case it will be the path to choose_press.sh. Note: do not use ~ there.
And in Trigger tab assign the shortcut. In this case we use f15 (use some way to simulate it, if it is not presented on the keyboard).
Start VS Codium
Use vs codium in X11 mode. This is because I currently do not know how to get active window class in wayland.
Result
Now if you middle click in vscodium window, it will receive the sequence of input that leads to enabling/disabling breakpoint. In any other window, the middle click will behave as normal.
There is debug.enableOrDisableBreakpoint in codium, but toggling that with shortcut only works when the cursor is on the line with breakpoint. I did not found a way to move cursor to the line where you pressed (method to get the mouse over line?). So I made that complex thing with ydotool choose_press.sh.
I also tried to start stop kbct by window activation, but that is unfortunately broken in kde wayland currently.
I'm using NetBeans 12.1 on Windows 10 with no plugins or other special setup. When editing any type of text file, pressing the escape key switches to a mode where the cursor keys scroll the viewport instead of moving the cursor. (In many editors, including NetBeans itself, this is typically done by Ctrl-cursor). Pressing escape again leaves that mode and returns to normal.
I often need to press escape to dismiss some window and frequently enter this mode by mistake. I then press the cursor keys to move the cursor but move the viewport instead.
I looked through key bindings to disable the binding, but couldn't find anything. How can I make NetBeans simply ignore the escape key in normal editing mode?
Default VS Code Intellisense behaviour
User is presented with a menu of suggestions
User then has to press the Up or Down arrow keys to navigate through the menu
Finally user has to confirm with Enter to insert the suggestion and close the dialog
What I would like instead
Don't need to press Enter
Suggestions are automatically inserted (and cycled through) by pressing Up/Down
Pressing any other keys will close the dialog and resume typing
To be clear, I want to replicate the default behaviour of YouCompleteMe:
When you type, a completion menu pops up. If you like the completions, you use the <Tab> key (by default, can be changed to <Enter> or <Down> arrow or whatever) to select a completion string you want. The very act of "tabbing through" the list to select the item you want inserts the candidate string. When you tab to a different candidate, the editor code is replaced with the new candidate. There is no accept key because by the point where you have the candidate you want selected in the menu the candidate has already been inserted in the editor. There is nothing to "accept". You just keep typing, the candidate has already been inserted.
Is such behaviour possible with Visual Studio Code, either by default or through a plugin?
The editor.tabCompletion option is the closest thing currently available:
By default, tab completion is disabled. Use the editor.tabCompletion setting to enable it. These values exist:
off - (default) Tab completion is disabled.
on - Tab completion is enabled for all suggestions and repeated invocations insert the next best suggestion.
onlySnippets - Tab completion only inserts static snippets which prefix match the current line prefix.
(Emphasis mine)
... except that the first Tab press hides the suggestion window.
I did some digging about editor.tabCompletion, and I found that closing the suggestion window is part of the tab completion's option original design, and that while other users have asked about an option not to close the suggestion window or specifically YouCompleteMe-style behaviour, that this is currently not supported.
"editor.acceptSuggestionOnEnter": "off",
To disable Enter to accept suggestion.
I use emacs in terminal mode. I know how to get the menu through F10 key. Emacs used to show the menu in terminal mode as text in a separate buffer. Either since a recent update, or I installed some package, I notice emacs starts to create a graphic drop-down list for menu items (see the screenshot). However, I only see it on one of my computer (Mac OS), my other computers still show the menu in "text mode". Can anyone tell me how to enable the graphic dropdown list menu feature? Is this a new feature of latest Emacs 24.3 or it can be enabled via some package?
This is described in the NEWS file for Emacs 24.4:
* Emacs now supports menus on text-mode terminals.
If the terminal supports a mouse, clicking on the menu bar, or on
sensitive portions of the mode line or header line, will drop down the
menu defined at that position. Likewise, clicking C-mouse-2 or
C-mouse-2 or C-mouse-3 on the text area will pop up the menus defined
for those locations.
If the text terminal does not support a mouse, you can activate the
first menu-bar menu by typing F10, which invokes `menu-bar-open'.
If you want the previous behavior, whereby F10 invoked `tmm-menubar',
customize the option `tty-menu-open-use-tmm' to a non-nil value.
(Typing M-` always invokes `tmm-menubar', even if `tty-menu-open-use-tmm'
is nil.)
Looks like a nice feature.
Several times now while programming in Emacs my keyboard has started to write Greek letters into the buffer. I assumed that I'd pressed some key combination but after searching I've yet to figure out what it is and my only solution right now is to restart Emacs. So what am I doing and how do I fix it?
Try to analyse what you've pressed.
M-x list-command-history shows command history
C-h l runs the command view-lossage which displays last 300 input keystrokes
I'm going out on a limb.
You're working on a windows computer that has multiple input languages configured (including greek). It also has the default keyboard shortcut to switch between them enabled (left alt+shift is the default, and if you have multiple inputs set up, it is on by default).
Some emacs shortcuts require an alt-shift combo, and depending on the order you press them, you get or don't get windows intercepting it for the IME switch.
Possible solutions include:
remove the greek IME
disable the windows shortcut to switch IMEs
change said shortcut
I typically want multiple IMEs on my systems, like that I can switch IMEs quickly, and don't want to mess with default shortcuts, so I ended up getting used to always pressing shift then alt when doing alt-shift combos in emacs.
