Homerow
Homerow label each button, link, etc. with letters, and click it when you type the label. It is like Vimium extension for Google Chrome, at the system level.
👨💻 I used to use Vimium on Arc and Google Chrome, also Vimari on Safari. With Homerow I can do even more with keyboard without reaching to mouse.
However, do not run it on UIs with too many interactive elements. It freezes the app and I had to “Force Quit” WebStorm before I remembered not to run Homerow when “Git Log” view is open.
