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
I confirmed that these already supported a number of terminals plus QT and GTK. They could also be mapped to be more ergonomic with a programmable keyboard:
But Shift+insert currently pastes the primary selection, not the copy-paste clipboard. So it doesn’t do the same as Ctrl+V.
It depends. In Firefox, Chrome and LibreOffice, Shift-Insert pastes the clipboard, not the selection. Viva Linux!
