How change all shortcut copy/paste other than Ctrl-C/Ctrl-V default, such as in Desktop Xfce and web browser or applications else

to have Ctrl-v changed to Shift-insert on startup, but it works only on terminal Xfce, or most term., still not work on URxvt.
So need such and Ctrl-c copy to be ctrl-insert
Please help solve, thanks before.
This doesn't do what you think it does. From
man 7 xkeyboard-config:
Most GUI applications which support shortcut keys like Ctrl+C/Ctrl+V also support Ctrl+Insert/Shift+Insert. The latter are IBM CUA (https://en.wikipedia.org/wiki/IBM_Common_User_Access#Description) versions of Apple's keyboard shortcuts (https://en.wikipedia.org/wiki/Cut,_copy,_and_paste#Popularization) adopted and modified by Microsoft.
Terminal emulators are a very special case. Some key combinations have special meanings in terminal input/output. For example, Ctrl+S will "freeze the terminal" (https://tldp.org/HOWTO/Text-Terminal-HOWTO-17.html#ss17.8) and not "open the Save dialog". Likewise with Ctrl+C.
What I'm using myself to copy and paste text from a terminal emulator is tmux (https://github.com/tmux/tmux/wiki) with tmux-yank (https://github.com/tmux-plugins/tmux-yank) plugin. It solves a number of other problems as well, for example scrollback buffer in st, the terminal emulator which I'm using. In tmux,
Ctrl+b [ enters "copy mode", where pressing "y" yanks (copies) text to clipboard and "Y" pastes it to command line.
