Set magic combo keys from Chrysalis gui

[jmorag]

Is your feature request related to a problem? Please describe. These doesn't seem to be any way to set combos as described in the docs

Describe the solution you'd like It would be nice if there were a way to set these from the graphical layout editor, but I'm not sure how a design for that would work.

Describe alternatives you've considered One could just write C. Can one write C for just a couple keys and then graphically set the rest?

Additional context The example linked in the magic combo docs: https://kaleidoscope.readthedocs.io/en/examples/Keystrokes/MagicCombo/MagicCombo.ino, is a broken link.
