When I first started my Linux journey about 23 years ago, I only ran it in text mode, since my computer didn’t have the disk space for X. I remember using Vim, and whenever I wanted to close it I would hit Alt-F4, which of course performed a VT switch.

When I inevitably launched Vim again on VT4 and wanted to close it, I obviously coudn’t, but I got the idea that Alt-F5 was a more powerful Alt-F4, so I used that.

After that I figured I was stuck and rebooted the machine.

and then you just press the power button

So true. Nuke it from orbit. It’s the only way to be sure.

This is true every time I go back to vim and promptly forget every keybind

If you think vim is bad for this, try dte :P
