A crafty AOL developer has created a little app called ScreenJot, which pretty successfully imitates the behavior for taking screenshots in OS X. I know there are lots of screen cap tools out there (feel free to suggest your faves in the comments), but this one I'll be using just because it's so close to the OS X method. With ScreenJot, you can hit Ctrl-Shift-5 and get a little crop tool, so you can grab just a section of the screen. This will drop a BMP into a folder called "scraps" on your desktop. While I wish it would save something more useful (like a JPEG), that problem is easily solved with any of the dozens of batch conversion tools out there...
