I do not understand what you are doing or the exact nature of the
behavior you are seeing (how are you binding F1 to an action, and what
is the exact action it is bound to?  what is happening when you press
F1?  What do you expect to happen?  What in the world is Tilda and how
does it relate to a terminal?).

However, an important thing to point out is that the WM does _not_
control keyboard focus.  The xserver does and the window manager has
limited hinting and observing capabilities.  Section 3 of "Why X is
Not Our Ideal Window System" is a great read on the subject --  As such, the behavior you are
observing may be entirely unfixable, or may well be a bug in an app
you are using (tilda?).

If you can dig up more details and explain the situation in more
detail, a bug report on bugzilla would be the right place to go.

Hope that helps,
