On Linux, Control-C and Control-V don't work for copying and pasting in terminals. The Control modifier is used for its original purpose of inserting control codes. Instead, terminal apps require an extra Shift modifier, like Control+Shift+C.
But what if there were hidden shortcut combos for copy and paste
It doesn’t open with a summary or overview but dives right in to exploration, but I think the point comes across:
The copy and paste key codes, which have no physical keys anymore, are - to a degree - supported in software. Their claim is that those key codes are the tool for universal copy and paste, and then it’s the input interpretations job (key and combination mapping) to offer bindings to those key codes.
… followed by some more “current state of support for those key codes”.
