Ctrl + A and similar selection manipulation shortcuts not working in visual code

Question

Select all, copy, cut, and paste are not working by using the usual keyboard shortcuts ctrl + a, c, x, or v.

Answer 1

for VS Code 1.55.1 I resolved this problem by 2 ways :

1. simply by uploading the keymaps of my long favorite editor as proposed by the manual https://code.visualstudio.com/docs/getstarted/keybindings:

so follow the menu :

File > Preferences > Keymaps

2. correcting manually the keyboard shortcuts which was in my case curiously corrupted, lacking of the necessary "when clause context" which was set with "-" However just open the keyboard shortcuts :

File > Preferences > Keyboard Shortcuts

Search the command "Select All" then right click on "When" (clause context) and select the "Change When Expression"

and tape :

editorFocus

which command to the editor "Select All" when editor is set as Focus on CTRL + A

I also faced the same issue like you in VS code.
It is probably because you installed the extension like Vim which changed the key binding like crtl + a and others.
To fix it simply, you just uninstall that extension and reload the VS Code and it should be working fine after that.
