Keyboard shortcuts

The more time you spend everyday working with computers the switch between keyboard and mouse sometimes becomes an annoyance. And if you are using a laptop then don't even ask about the issues between switching from keboard to the laptop mouse.
I recently came across a great artcile about Productivity Ninja 101 keyobard short cuts. The list is simply amazing and Firefox short cuts are my favorite especially quick search using / and reopening closed tab using Ctrl + Shft + T.
A very very useful shortcut key mentioned in the post is F2 to edit a cell in Microsoft Excel. I will let you enjoy the article and make good use of the shortcut keys.
To add to the list are couple of more shortcuts you might want to try out

2. IE, while typing the web address press Ctrl+Enter enters the www. and .com and for Firefox additional support with Ctrl=Shift-Enter adds .org, and shift-enter fills in .net is provided.
