I don’t know how many people take screenshots on their machine like I do. As they say “A picture is worth 1000 words” and I think it would take a lot of words to describe just how useful I find this. When I have had to do this in the past, I used either a program like Snagit, or I would do the Alt-PrintScreen and paste into an image editing tool like Paint.Net. Then I would crop the picture to what I want.
With Windows 7, my approach is going to change. Shipping with the beta (and hopefully the final release is a tool called Snipping Tool. This let’s you snip a screenshot and save it to image format of your choice.
Once you snip it then it opens in the snipping tool editor where you can save it, mail it or use the drawing tools to write on it with a pen or highlighter. The eraser will erase the pen or highlighter marking that you make on the snipped image, but not the underlying image.
It may not have every feature that you want, but it seems to be a useful tool and saved me some time already.
