I’ve used tmux inside a single vterm buffer for several years now, and together with vterm-toggle to toggle buffer visibility with a single keypress, it’s been a nearly perfect setup (apart from vterm-toggle messing up winner-mode’s undo history). I remapped the default tmux operator key to ‘;’ so it kinda logically fits with devil-mode, which I’ve been using for a few months.

I’ve also augmented vterm with custom functions, such as I can quickly cd to another dir using ivy completion in the minibuffer, which is much faster than using shell’s integrated completion system.

Since my work laptop comes with windows and no way of remapping caps lock with ctrl (for real, powertools can’t be installed according to company policy), I was forced to look for alternatives. IIRC, first version of devil mode had just come out and while that version didn’t quite do what I wanted, the newer versions are so good that I rarely miss the standard way.

Basically made my job tolerable.
