If I remember correctly, there's a bug with the Input Setup tool in beta3, so I was trying to decipher some of the code in order to get the Calendar, Address, & Home buttons mapped to some apps. When I got to the /mnt/smb/etc/xdg/openbox/rc.xml file, I noticed that there are keys defined for switching desktops!
I had no idea that pdaXrom supported multiple desktops! And I had never hit the Ctrl-Alt-Left/Right keys to accidentally discover this. Am I the only one who didn't know about this?
Now I'm wondering how many other cool features I'm completely unaware of.
