I am used to Ctrl+Insert as my shortcut for "Copy to clipboard". Also Shift+Insert for "Paste" and Ctrl+Delete for "Cut".
Recently, these shortcuts stopped working in Notepad++. I don't remember if I updated it to latest version. When I go to Notepad++ menu "Settings" -> "Shortcut Mapper", I see that Ctrl+C is mapped to the "Copy" command. This is good, but I also want Ctrl+Insert to do the same. When I try to change the mapping, it deletes the Ctrl+C mapping.
How can I map two shortcuts to the same command? Is it only possible for a few commands (like Copy, Paste and Cut) and not generally?
