        Hi,
I suppose you selected the folder by mouse. As such, the folder tree on
the left is focused, thus it gets the keyboard input...

... unless the keystroke is defined as a short cut for some action,
then the action is executed instead the keystroke being used by the
focused widget.

That might be due to the GtkTreeView, which, intentionally, doesn't
change background of the selected item in it to some "grey" from "blue"
when the widget loses focus, which for example the message list does
(the actual colors depend on the current theme). There is a bug report
against gtk+ and GtkTreeView for this, resolved as that's on purpose.
