On #Windows did you know that the programs you have on your taskbar can actually be accessed quite quickly. The icons are ordered starting from 1 to 0 (0 being the 10th item) so just press the Windows Key+1 etc and open the respective application quickly.
If you press the Shift key along you will be able to open multiple instances of the application, really helpful when you want to open multiple windows of an internet browser or file management system.
