Get selection from an internal command such as "commandline get-selection"

[blindFS]

I'd like to add keybinding features like vim-surround to vi normal mode. As far as I know, I can't get selected text or copied text (not the system copy/cut) in pure nushell script. It would be even better if commandline edit support more actions such as those already existed in keybindings list --edits.
