After a long break from coding (longer than what I’d wanted by half), I’ve started working on properly implementing modifiers for the keymapper, instead of feeding every key in an additional time for each possible combination of modifiers that exists.
I’ve got it halfway working in a temporary way — it only feeds the keys in once, but the remap dialog can recognize modified keys and tell that they are different from unmodified keys (and that ctrl-a is different from shift-a), but events mapped to modified keys aren’t triggering at all for some reason.
The more important thing, though, is that I’m back in the swing of coding and getting work done again. Hopefully I should be back up to full speed in another day or two.
