neovim: "bring" onto the command line

[saidelike]

It would be useful to be able to bring something from the buffer (text editor or terminal) onto the command line. An example is when renaming a tab using :TabooRename <name> and name is present into the buffer

it might be really easy to do because it's very similar to bringing something into the terminal prompt except we want to detect the command mode, so may qualify for a good first issue to learn about Cursorless in neovim.
