# Seperate Alt Mods in dwm via xmodmap

Using the left and right Alt keys as 'seperate' modifiers is for some
reason more difficult then expected in dwm. For my usecase I just want to
use the right Alt key as a passthrough 'non-WM' Alt key for applications
such as helix which utilize Alt for some functionality.

After some trial and error what I realized is that a good solution is
to just remap left Alt to another Mod, and then set dwm to use that mod
(thus only affecting the left Alt key and leaving the right Alt alone).

In .xinitrc:
  xmodmap -e "remove Mod1 = Alt_L"
  xmodmap -e "add Mod5 = Alt_L"

In dwm config.h:
  #define MODKEY Mod5Mask
