With the GA of Windows 8 just happened a few days ago, I started to put together an article of tips and tricks. Putting up the shortcut keys is definitely on my list.

So here we go --

Moving between Metro and Desktop

• <Windows>      
  Brings up the Metro start screen. You can start typing to search for an app, just like the Win7 start menu.
• <Windows> + <B>      
  Go to the Desktop from the Metro Start Screen
• <Windows> + <D>      
  Brings you to Windows desktop from the Metro Screen

Snapping

  snap right

  snap left

Switching between applications

• <Windows> + <Tab>      
  Opens the Metro application switcher menu, switches between applications.
• <Windows> + <J>      
  Switches focus between snapped Metro applications.
• <ALT> + <F4>      
  Close an application
• <Windows> + <R>      
  To bring up the run window from the desktop, so you can type in an application name to run

Semantic Zoom

• <CTRL> + <+>      
  Zoom in
• <CTRL> + <->      
  Zoom out
• or hold down <CTRL> and use Mouse Wheel to zoom in and out

Displaying App & Charms Bar

• <Windows> + <C>      
  Brings up the Charms menu, where you can search, share, and change settings.
