Keyboards with custom firmware that support dedicated "Copy" and "Paste" keycodes are more common now.
These keycodes solve a pain point with terminals: that you have to use Control+Shift+C/V to paste into the terminal, but Control+C/V everywhere else.
The dedicated Copy/Paste keycodes solve this problem by allowing you to use the same key combo in all apps that support it.
This patch supports the additional bindings by default while leaving the existing keybindings untouched.
keyboard input has changed a lot in iced, but I think I've made the proper adjustments here. vertical splits don't seem to work, but that didn't seem to work before either. Also, there is a black border on the right and bottom of the first tab of the terminal. I'm not sure why yet, but it seems like it is probably related to the scrollbar
