`Ctrl+/` should automatically remove start brackets

Enhancement Request

Explanation

In most languages, at least in VSCode, Ctrl+/ is a shortcut that automatically comments the selected line, or a selection of lines, or if the line is already commented, uncomments it.

This would be a neat feature to have at some point. What it would do is remove the [ from each token in the selection, replacing them with some other special character (maybe {, we could brainstorm a bit). Using Ctrl+/ over a selection would convert any instances of this special character back to a [.

And thus this would be a way to quickly and easily comment out (or uncomment/reactivate) large numbers of tokens.
