I wrote a keyboard hook in C for Windows (I was using AHK but it was unreliable). Initially it was modal but I found over time that I would get caught out. So now it's not modal. I hold down capslock and then use ijkl to navigate etc. The only thing left that is modal is spacebar for select/visual mode but I still a have to hold down capslock for that (e.g. capslock down, space bar, ijkl to select text, capslock up). Also I was using hjkl but switched to ijkl to match the arrow keys. I don't use vim enough anymore to justify hjkl.

Holding down capslock turns out to not be a problem in practice. The main benefit of vim style navigation for me is not leaving the home row.

Same here. ijkl is so much better!

Hmm… maybe I should try that. Then again, I am afraid of getting the Emacs pinky all over again…

In my case, the interval is set to 0.5 which has a slight delay but enough for me to not mind. I usually have a mental idea of what mode I am in at all times.

Check the arch wiki article on Cursor themes[0]. Generally,, DEs have nice support for switching cursor themes after startup. In either case, you would need to modify `xkb_swapper.sh` to set a cursor theme whenever the mode is changed.

Oh cool, I hadn't noticed that you were actually around here on HN! Thanks so much responding!

I noticed that more frequent updates of the status bar do eat away at the battery, though. :\
