Couple UX improvements

[cogscides]

I'm using metaedit to create or change values with easy, but when I have several values it becomes a bit tense. The reasons why this happens:

1. Entering values After I select a value in the list with the enter key, I have to press enter key again to confirm the entry. When there are 5-6 keys, it becomes difficult, also there are no placeholders. The process can be brought to the state as implemented in templater.

2. Quick value selection It would be nice to have a hotkey to change the value, which is on the same line as the mouse pointer. Thus in one key combination, selection, and one click enter, you can quickly make changes.
