On my keyboard I have two annoying keys right next to the arrow keys that go to previous/next page and I’ve always used them accidentally and have lost my drafts. Here is how I’m going to remap them so that they work as home/end buttons instead. The following command opens a window and captures all key presses on keyboard.
xev | grep -A2 --line-buffered '^KeyRelease' | sed -n '/keycode /s/^.*keycode \([0-9]*\).* (.*, \(.*\)).*$/\1 \2/p'
If I press the two annoying buttons and the home and end buttons, this is what I get:
166 XF86Back 167 XF86Forward 110 Home 115 End
The plan is to map 166 to 110 and 167 to 115. Create a file at ~/.Xmodmap and add the following lines to it:
keycode 166 = Home keycode 167 = End
Or if you don’t want them to do anything, map them to something like F13 and F14 which are usually non-existent.
Save the file and run the code: xmodmap ~/.Xmodmap and you are good to go. Add the line to your ~/.bashrc and you don’t need to repeat this ever (hmm, this requires a new bash session to be initiated before the mapping takes effect). You can add this as a cron job whenever your computer boots so that you don’t need to open a terminal every time before you go on your merry way of browsing the internet etc:
- Run
crontab -e - add the line to the end of the file:
@reboot xmodmap ~/.Xmodmap - Save and exit and check if it is there:
crontab -l
Or you could do it other ways: https://www.simplified.guide/linux/automatically-run-program-on-startup
