Set it to capture, in the settings set it to capture the entire window and then use the hotkey (I use F11) and when you're ready you can just press F11 and it will capture all of it. If you mean do you want it to do something like scroll and capture all of it if the (say browser) is larger than a single instance of your screen then it doesn't do that.
For that I am lucky and am gifted an application called SnagIt. They give it to all Microsoft MVPs. That will enable you to do scrolling screen captures and is really rather nice.
So I took a trip over to a freeware site that I know scans for malware such as spyware and adware...
Something here might do it:
