Here are some of my favourite Window shortcuts. While you might say but I can click with the mouse you will find if you master some of the more common commands can make you work faster and without interruption.
Try them out:
F1 – Windows Help
F10 – Shows menu options
CTRL + ESC – Opens Start Menu
CTRL + SHIFT + ESC – Opens the Task Manager Dialog box
ALT + F4 – Closes the application or current window you are in
Windows + M – Minimises all windows to desktop
ALT + F6 – Move between multiple windows in the same program
ALT + TAB – Move between open programs
