⌨️ Shortcut Keys on my Mac
With command+v set to pasting, as default on macOS, I set shift+command+v as clipboard history using Clipy. The additional shift key requires your pinky.
One of my favorite is command+`, which toggles a fullscreen, transparent iTerm2 screen. It feels like a Quake console for cheating, but more awesome!
