Incidentally, high keyboard repeat rates is an important reason why I prefer spaces over tabs —- so that the horizontal cursor speed remains constant. (I’m serious.)
> set your keyboard repeat rate to 100 keys/s.
also, you can reduce the delay so that repetitions start sooner. With some practice and care you can reduce the delay to about 0.15 seconds and learn to fly over your keyboard
xset r rate 150 255 # delay=150 (milliseconds) rate=255 (keys per second)
If you are on sway you can do the same: https://wiki.archlinux.org/title/Sway#Typematic_delay_and_ra...
To see the default value use xset -q
Upside: works anywhere, much lighter mental load, relatively easy to learn and adjust to.
Downside: some programs (ironically, mainly Emacs) can't keep up, and scrolling becomes choppy.
On Linux this is quite easy. When I was using Windows, there was no good solution for USB keyboards, so I hacked up a driver to do it: https://github.com/CyberShadow/KeyboardEmperor (signing keys not included).
