Ok try these bitches:
Windows Logo + C
Windows Logo + D
Windows Logo + I
Windows Logo + Q
Windows Logo + F
I upgraded last night to check it out, only £25 which makes it worth a go.
Have to say I'm pretty much just using it in desktop mode at the moment, browser etc works way better in desktop mode especially if you like to have multiple tabs running.
Is a bit random just hovering around in place but I'm sure once you get used to it it will be quick enough.
Those shortcuts however are perfect, make things so much easier to use.
