Ctrl Z is the magic undo combo. It simply undoes your last action, say, the paragraph you accidentally erased (it works in other applications, too–try it on the Photoshop filter you really wish you hadn’t applied, or after renaming a document or a folder in a Windows directory). Programs vary in the number of times you can undo something, but some will let you Ctrl Z all the way back to the beginning. (And, yes, there is a redo command, just hit Ctrl Y.)

This is one more Awsome site… Worth giving a visit…Just search something …on the left side of the screen u have..yahooo search results and on the right u have google results.. amazing isnt it

One of my friend messages me to just check out www. blackle.com and i did.I was stunned at the site ….Its nothing but another version (black version of google search)….. There s a reason actually to start it…Here it is…
Blackle saves energy because the screen is predominantly black. “Image displayed is primarily a function of the user’s color settings and desktop graphics, as well as the color and size of open application windows; a given monitor requires more power to display a white (or light) screen than a black (or dark) screen.” Roberson et al, 2002

In January 2007 a blog post titled Black Google Would Save 750 Megawatt-hours a Year proposed the theory that a black version of the Google search engine would save a fair bit of energy due to the popularity of the search engine. Since then there has been skepticism about the significance of the energy savings that can be achieved and the cost in terms of readability of black web pages.

We believe that there is value in the concept because even if the energy savings are small, they all add up. Secondly we feel that seeing Blackle every time we load our web browser reminds us that we need to keep taking small steps to save energy.
