That sounds simple enough.

Stepping through contents in that case should be done by arrows I
believe, some plugings may accept vertical stepping (such as desktop menu
categories for example) and some horisontal (such as pager or launcher)
but some may do both.
The implementation is also trivial:
1) the panel should accept some keybinding to receive keyboard focus such
as Alt+F1 (for example); it receives keyboard focus and places focus on
the first (leftmost) plugin;
2) Tab moves focus between panel plugins; GTK actually does that already
if each plugin presents a widget on the panel, which I believe is the case;
3) plugin accepts keyboard events to iterate through own things.
So very few things should be done really:
1) allow the panel to receive focus by some way (it is omitted from pager
by default and therefore cannot receive the focus);
2) implement keyboard events support in each plugin (some of them already
do that implicitly by implementation, BTW).

I believe that moving to Qt should never mean we have to drop all the
GTK2 support since due to numerous reasons people still may need Gtk-only
desktop, at least while GTK2 is still in use.
