I was just working through this article and the database - http://wiki.linuxmce.org/index.php/Hardkey_And_Button_Mapping
The default key mappings for my onscreen orbiters are all the same and includes a first line of:
10 0 -300 1 741 159 1
From my reading of the article and the database, this seems to suggest that key 'F1' (mapping 10) sends a message of "command" type to the local Orbiter (-300), with a command number of 741 which means Goto Screen, and the screen specified (1) is Main. But when I modify this to a different screen number, regen and reload, it still does exactly the same thing. Moreover, 'F2' is mapped to "back" but also calls up Main. And F6/7/8 do specific things, but there isn't any mapping for them in this devicedata field...
What am I missing?
