Not sure if this is obscure or not: I have F12 bound to cycle through the low- to high-contrast versions of my color scheme so I can keep working when the sun hits my shitty laptop screen.

Not a Vim user, but no matter what software I’m using, I might think about its keybindings like the first week of getting familiar with it; at one point they become muscle memory and I stop thinking about them.

All hail nano
