I do a lot to reduce context switching even on the small scale, and reducing how many times I switch to the mouse is one of those things. I also reduce screen switching, "alt-tabs" or workspace switching, for that I use a tiling window manager (i3). Since it's impossible to avoid web browsing for work, I also use Vimium to bring more keyboard into that process. I would consider my approach "low-mouse" rather than no mouse. Certainly not no-keyboard. Although not quite voice activation, if you can type then typing is concise and accurate, which makes it quick. Does anyone have any experience comparing this to Vim?

Especially for Vimium (chrome extension, not Vim), I consider it a superpower, because it feels a bit like telekinesis. I can just look at things and make them happen with my keys, no need to navigate toward them.
