Tab suddenly stop tabbing in VSCode? Try hitting ctrl+m — evidently there’s another ‘mode’ for the tab key where it changes focus instead of tabbing. Very cool and useful when used deliberately. Very “huh?!?!” when you accidentally hit ctrl+m 🙂
|Ctrl+M||Toggle Use of Tab Key for Setting Focus||
Of course if that wasn’t your problem … focus mode is turned on now & you’ll want to hit ctrl+m again to change back to tab mode!
