[FEAT]: Shorthand values for mod combinations

[KohlJary]

When writing a configuration with a lot of bindings involving modifier combinations, IE: "ctrl + shift +", it gets repetitive having to type in the same list of modifiers for each binding. It would be helpful if there were special case values that one could use as a short hand, such as:

cs
as
ca
cas (meh in QMK)
caws (hypr in QMK)

This would make configs a lot easier to parse at a glance, at least for me. Planning on using meh as a workaround for the Win key system shortcut issue in windows, and would save me a fair bit of repetition in getting all of that configured.
