Most editors support pressing 'shift+delete' to cut, which makes cutting and pasting fast using when using it together with 'Shift+Insert' to paste. (vs ctrl-c / ctrl-v). Proton Docs (tested using Firefox on Linux, but possibly on all platforms) deletes the selected text when hitting 'Shift+Delete', but does not Cut it, causing a subsequent paste to paste whatever was in the buffer. 'Shift+Insert' does Paste, so errors are easy with this method. Please add functionality to have Shift+Delete perform a proper Cut operation, and store the deleted text on the clipboard.
