Copying and pasting from a terminal emulator on LInux is a pretty common thing to do, to say the least. But pressing CTRL-SHIFT-C/V is a one-way ticket to carpal tunnel syndrome.
After searching for over an hour for "how to make CMD-c and CMD-v (or WIN-c/v, my keyboard is from my Mac era) do copy/paste in Linux globally, turns out a much simpler approach is to stick with CTRL-c and CTRL-v but remap CTRL-c not to do an "interrupt" at the terminal (e.g. Wezterm) level. Now to "interrupt" a CLI command/process, I have to press CTRL-x instead of the classic CTRL-c, but imo it's worth it to keep CTRL-c/v as the copy/paste everywhere. It works out because CTRL-x as in "cut" is almost never something I do in a terminal emulator. In Libreoffice, sure, in the browser, ok, but in the terminal...doesn't usually come up.
Posting for those who else ever got sick of needing to do CTRL-SHIFT-c in the terminal but CTRL-c in, for example, the browser.
