Heh, shortcut muscle memory is the reason I returned my Mac mini one week after trying it. I sure am not gonna remap my brain for apple after 20 years of Linux and windows.
So yes keyboard remapping is an option. But there's just differences you can't remap because of the extra meta keys on Mac (and I guess on Windows too, with the Copilot or Start keys in play).
Right, and even on Linux you can do it by using the four-fifths forgotten CUA shortcut Ctrl-Insert for copy (and Shift-Insert for paste.) Although I'll admit to using Ctrl-Shift-C/V most of the time.
