It doesn’t have to be on a computer.
On my keyboard, I use left alt as a layer for vim keys outside of vim, caps lock as ctrl, and right alt as escape. I’ll combine them so I can move forward and backwards a word or delete/backspace a full word.
What kinds of things do you do?
Yes, stuff like this saves me so much time in the long run. I have shortcut abbreviations I type for my zoom link, bookings link, phone number, email. Generic ticket closing response. Hex codes for colors in my work palette. Even kind of long bits of code when I find myself reusing them frequently.
