/* The caps word concept started with me @iaap on splitkb.com discord.
* However it has been implemented and extended by many splitkb.com users:
* - @theol0403 made many improvements to initial implementation
* - @precondition used caps lock rather than shifting
* - @dnaq his own implementation which also used caps lock
* - @sevanteri added underscores on spaces
* - @metheon extended on @sevanteri's work and added specific modes for
* snake_case and SCREAMING_SNAKE_CASE
* - @baffalop came up with the idea for xcase, which he implements in his own
* repo, however this is implemented by @iaap with support also for one-shot-shift.
* - @sevanteri
* - fixed xcase waiting mode to allow more modified keys and keys from other layers.
* - Added @baffalop's separator defaulting on first keypress, with a
* configurable default separator and overrideable function to determine
* if the default should be used.
