Xmodmap example

.Xmodmap

! # NOTE
!
! For asian users, this keymappings will not work when typing in your native
! language. You need a separate article to understand why that doesn't work,
! yet you can use keyd or kmonad if you need low-level global key mapping.
! I personally recommend using keyd if you are not familar with lisp-like
! languages. 
!
! - Keyd repository : https://github.com/rvaiya/keyd
! - My config for keyd : https://gist.github.com/Simhyeon/58b008a9a5d8e8b34d78d774db1f745b

! If you want to change .Xmodmap by your flavor refer to the table in the
! bottom of this file. Also Arch wiki is a great resource.

! # How to get keycode
!
! Keycode can be detected with xev command. Simply open up your terminal and
! type "xev" to find out. Search for Key even block which contains keycode
!
! Especially use a command 'xev | grep --line-buffered keysym' if you want some
! intuitive keypress sequences.
!
! # How to use xmodmap
!
! Simply run "xmodmap .Xmodmap" in your shell. If yout want the script to be
! ran automatcially on boot, use system service or startup script preferrably
! time intervals.

! # Clear keys
! You should clear special key that you want to change bofore assign other keys 
!
! Clear special keys(left_alt) and reassign it as mod switch key
clear mod1

! # Mapping
! Set custom key mapping
! Key mapping are separated by whitespaces and a syntax is quite lenient
! Key code mapping table's format is in the next line.

Well darn it. Can't figure why indent is a mess.

Thank you so much for sharing this. I probably don't have a good understanding of how xmodmap still works, but does alt+tab work for you to switch between different windows?
