Some people (“Us old school folks) know that there was a time that a computer could be used without using a mouse.  The feature referred to as Keyboard shortcuts still exists today (even though most current users don’t have a clue that its there). 

So in the interest of not getting this question 1,000,000 more times here are some very helpful shortcuts for Internet Explorer.

ALT+D – Put focus in the address bar, and select whatever text is there
CTRL+ENTER – Put ‘http://www.’ and ‘.com’ before and after whatever text is in the address bar
ALT+LEFT – Go Back
ALT+RIGHT – Go Forward
BACKSPACE – Go Back
ALT+HOME – Go Home
F11 – Enter/Exit Full Screen Mode
F5 – Refresh
CTRL+F5 – Refresh from the site your on (Forces re-download of page instead of refreshing from cache)
ALT+V, B – Toggle the Status Bar
ALT+A – Open the favorites menu; then type the first letter of the favorite you want
F6 – Move focus between major UI elements (Toolbar->Explorer Bar->HTML Page->Toolbar)
TAB – Move focus between minor UI elements (Link->Link in a page, Address Bar->Go Button, etc)
SHIFT+TAB – Like TAB, but the other way
SPACE – Scroll the page down (same as the PageDown key)
These shortcuts apply to all normal windows applications, not just IE:
ALT+SPACE, X – Maximize the window
ALT+SPACE, R – Restore the window
ALT+TAB – Switch between top level windows
SHIFT+F10 – Display the context menu (similar to Right-Clicking)

     This list is just for Internet Explorer, there are more shortcuts for Windows and other software.
