it would mean:

* another setter in Applet
* another QString we hang onto for the life of the Applet object

couldn't we just put a generic "Activate" string there instead? not precise, 
but i'm not sure precision matters here (esp at the costs above)

we already have an addAction() method. if the action is added there we can 
allow a shortcut for it.

right ... or we could just use the KShortcutsEditor widget there even, after 
filtering out the 'global' actions (remove, configure, etc)

the panel unhiding and activate() being called are two wholey unrelated 
activities. in fact, panel unhiding is completely transparent to Containment 
and must remain that way (it's a View thing, and in this case a View thing in 
plasma-desktop; don't think of "plasma" as "that binary called plasma-
desktop", as plasma-desktop is just one possible incarnation of things, and 
those other things may have no panels or no panels that can hide; this means 
that Containment and View must be kept as separate as possible.)

so when the global shortcut is triggered, the applet will say "hey, i think i 
need to be seen now" and that will percolate up through the containment and 
then thew view might say "oh, i have to do something special now"

for DesktopView that might mean calling forward the dashboard or invoking 
"show desktop"; the PanelView that might mean unhiding. for another View it 
might mean nothing at all :)
