TUI - how enter should work on the radiobuttons or trees

To be checked and then discussed.

Now:
We can see this in at least two places, where we switch working account or select the file from tree using buttons (not mouse).

So I am on the switch working account window:

1. I use arrows to choose the working account.
2. Then I press enter and the working account is marked as chosen.

I would expect that if I press enter one more time, my choice will be confirmed, new working account will be set and window will be closed.

Please do research if it is expected behavior for radiobutton and trees.
