Describe the solution you'd like?

A number of modern keyboards now support the Copy and Paste keycodes.

These are useful in terminals, because terminals usually require Control+Shift+V for Paste for example, while Control+V is used for Paste everywhere else. The Paste keycode allows for a keyboard shortcut that works for pasting both inside and outside of terminals.

The Copy and Paste keycodes are supported by a number of other terminals are usually a one-line fix to add.

For an example in Rust, see how these were added to cosmic-term:
