Windows 8 hotkeys
Few Windows 8 hotkeys I have found useful:
Win
Goto start screen, start typing application name to search for it
Win-X
Open advanced menu from bottom-left corner of screen (you can access this by right clicking mouse on same place)
Win-X + A
Open command prompt as administrator
Win-X + C
Open command prompt (this is better than just launching command, the shortcut always creates new window)
Win-W
Access the search dialog. Search is not just for files and folders. Try typing for example “path” immediately after Win-W and you get choices which you can use to go the user or system environment settings.
Win-Left/right
Dock window to left/right side of screen, move around displays if you have multiple
Win-Up/down
Maximize, restore window
Shift-Click
Open new instance of programs
Middle click
Open new instance of program
Ctrl-Shift-Click
Open new instance of program as administrator
