    You know of course that 
WindowsKey+D shows the desktop and this includes hiding the 
Sidebar. If you want to show the desktop but still have the Sidebar (and any floating gadgets) visible then hit 
Win+M. If at any point you need to bring on top the Sidebar and gadgets regardless of what other windows are showing, hit 
Win+Spacebar.
Now the new ones I only learnt this week (shame on me I know): 
Win+G will cycle through the gadgets and while a gadget is selected, 
Shift+F10 will bring up the context menu. Am I missing any other relevant shortcuts?
