Support pressed key combinations that output alternative keys

[jackfranklin]

One thing I miss when compared to a QMK board is the ability to define key press combinations.

For example, I have a combination of JK (when I hold both down at once) to actually output Control-Y, which is my Vim keybinding to accept an autocomplete suggestion.

Describe the solution you'd like
I would like to use Chrysalis to register these combinations - enabling me to trigger a macro when two (or more) keys are pressed. As far as I can tell, it cannot do this currently (I'm not sure if this is even supported by the keyboard so feel free to tell me if this is impossible).

Here is the relevant QMK guide (via the VIAL app, which is a GUI): https://get.vial.today/manual/combos.html

Thanks!
