How do you discover key combos in Linux?

[OJFord]

You read the man page/documentation for the software you installed that they're for, or else you defined them yourself and don't need to discover them.

Apple also provides ample documentation

Sure, but the complaint was discoverability, my point is that on Linux you start with something you don't need to discover: you either defined the shortcut yourself, or you installed something that defines it by default. There are no 'system shortcuts'.

Generally speaking, you dont actually need them in Linux, you can do everything with mouse.. however you can't actually use macOS without them.
