If you are like me and sneak on the computer while you are at your office job then you need to know some things. To clean your internet history in internet explorer go to Tools, click Internet Options, Delete Cookies then click ok to get rid of Temporary Internet Files, then click Delete Files, Delete all Offline Content, then click Clear History. Now if your boss is savvy with computers he can still get IT to check what you can't delete on their server but most non IT related bosses don't know that and its also good to do this regulary(I can't remember why but someone told me) Also here are some shortcuts that I use on the keyboard.
My favorite is Alt+Tab- switches pages, so instead of using the mouse you can go back to your workload and switch back and forth to the internet quickly :)
Here are a few more
Ctrl+N- creates a new page
Ctrl+Z to undo the last thing
Ctrl+C- copy(this is good when right clicking is disabled)
Ctrl+A- highlights everything on the page
Any favorites that you may have or willing to share? I can always know more. :)
