I bought a Dell tablet and I really liked it except for when I really needed to get some work done which is when I started hunting for a bluetooth keyboard.  Since I'd already purchased the nifty aluminum keyboard from Apple for my iPad, I connected it to my tablet.  All was well in the world until I started looking for my favorite Windows keys.  Stumbling upon this site, I found that 'some' of the combos work, others not so much but I still think it's helpful nonetheless.

The one that really drove me nuts was the Windows delete key which can be had by simultaneously holding the CTRL and D key.
