I recently walked into a pretty esoteric issue for people who don't with terminal emulation often :

Having rebound at firmware level my `Left Ctrl` key to `F13`, I found that while the key was appropriately grabbed at the OS and terminal emulation level, it wasn't really making it to my weird Zsh setup[1] and it couldn't be bound through `bindkey`. And I couldn't really change the keyboard binding to anything else because everything's already configured to use `F13`.

I ended up looking everywhere for what scancode I should be reading on the command line, and found this endlessly useful little cheatsheet.

In the end I configured the terminal emulator to output `\u001b[25~` on `F13` inputs and now it kinda mostly works.

[1]: The culprit is [Zsh Vi Mode](https://github.com/jeffreytse/zsh-vi-mode). It's great !
