The mouse is a little out of the way. Seems like have you to move to a workflow that you are almost entirely on keyboard? I would love that but just find that there is so much forced mouse interaction which I would like to avoid?
If you just need to click a button or two now and then, keynav is great. It’s one of the programs I have in a script to fetch automatically on fresh GNU installs, though it’s no replacement for vi bindings everywhere one can get them (vis, dwm, tmux, Pentadactyl, etc.)
