.Xmodmap

keycode 117 = End

readme.md

1. First identify current keycodes by running xev in the terminal
2. Create a file in the home directory with name .Xmodmap
3. Inside of the file, remap the keycode with desired keyName

for me, I waant to replace Next key into End key.

110 Home - HOME
115 End - END
112 Prior - PAGEUP
117 Next - PAGEDOWN

to do ths, I added keycode 117 = End which determines keycode 117 is now work as End key

4. After typing desired keycode and name accordingly, save the file as .Xmodmap in home direcctory.
5. then run the command xmodmap ~/.Xmodmap from terminal.

That's all. you are now all set
