Yes, don told me via PM that buttons have no effect.
From the source code I don't see the F6/F7/F8 so it looks like I'll have to recode it...

For the menu, try to reboot. Maybe it will appear. Usually packages will update the menu after installation but sometimes the update doesn't work.
At boot, the update-menu is run so it should create the entry.
If after a reboot, it's still not present then it's a bug.
