Yes. As a long time Emacs user I do that routinely on _every_ machine I use.

For those that don't know, there are a handful of control key sequences that perform basic cursor movements that are the same in Emacs, bash, zsh, and every text pane in Mac apps. Using caps lock as a control key makes this very pleasant.

I am unlikely to give up this habit since I despise moving my hands from the home row to use arrow keys -- for me, this is the main pain point when switching between Windows and Mac several times per day.
