Copilot: allow to accept only part of the suggested completion

Hello,

The copilot plugin works great, but it would be very nice if a part of the suggestion could be applied. Sometimes we get 5 lines, but only the first 2 are ok. Now it's accept the whole thing and delete the extra's. It's also not only whole lines, but sometimes just the first part is ok and the rest of the line not. So with that problem, it would be nice to allow for example to use the arrow keys, or maybe ctrl+arrow keys to select only the part you want to accept. And then press enter to accept the selection.

Best regards
