If anyone wants to have this style but in an actually usable keyboard, you can buy (at great expense) these keycaps and put them on whatever cherry-mx-compatible keyboard you like:
Does anyone know if the thing that looks like a key in the middle of the four directional arrows is actually a key? If so, does it have a default key binding (it doesn't appear to have any symbol on it)? It it is an actual key, I assume that it can be mapped to something (presumably to replace one of the three super-common keys that they left out because this is intended as a meme keyboard, not a serious daily driver, but we all know that isn't going to stop some people from using it that way.)
Easy, use Ctrl-[ instead! It’s no different than pressing Esc, at least in terminal.
> So even today, on Unix-like systems, applications running in a terminal emulator receive the character Ctrl-I when the user presses the Tab key, the character Ctrl-[ when the user presses Esc, etc.
Not so fast, if you can do `:` (i.e. enter command-line mode) then you can do plain `:q!` - no Esc or Ctrl needed.
How I understood the original problem is that you're in vim, you started editing text (insert mode) and now want to exit; but there is no Esc, so even exiting insert mode is a challenge. And now you added the constraint of missing Ctrl too, so no Ctrl-[ or Ctrl-C.
If you type `:.! kill -9 $(pgrep -u $(whoami) vim)` then you just entered that as text into your document.
One answer could be to use the trackball, launch a new terminal window and kill the process from there.
Fast access for the left pinky and makes for some nice mental symmetry in having the right pinky bound to Enter (Yes) and the left bound to Esc (No).
The only downside is when you're on someone else's machine and suddenly start typing in caps :)
