I am a keyboardist: using the mouse is slow and annoying. There are many temporary files that I wish to just close with two or three keystrokes apiece. Instead I'm presented with this dialog for every file: and the buttons can not be navigated either by mnemonics or by tabbing. I am being forced to click on every one.
I've been living with this for a couple of years: but is there any option to get standard tabbing ?
Pretty sure you could do this by switching to custom dialog styling. Ex. put this in your settings.json file:
"window.dialogStyle": "custom",
This will make VS Code render the dialog within itself instead of using the native OS / Desktop Environment / Window system. You may even be able to use arrow keys (I haven't tested this on all dialogs, but it definitely works for some).
