Why are not all key symbols recognised in i3 config?
The user guide suggests using xmodmap -pke or xev to figure out key symbols to use with bindsym in the i3 config. However not all key symbols are recognised, e.g. Alt_L (key code 64).
How is the user supposed to know that you need to use the modifier keys Mod1 rather than Alt_L and Mod4 rather than Super_L?
