Mouse Click & Scroll

One thing that drove a former co-worker absolutely crazy was when he was zoomed into an image in Photoshop and was using the lasso tool, but because he was zoomed in so far, he couldn't see the whole image. When he tried to scroll without letting go of the mouse, Photoshop of course went crazy with the selection.

His rather creative solution, though a lot of work, was to use the Lasso Tool to make his selection of what he could see on screen, save it as a channel, then scroll the document and repeat until he had everything he wanted. I didn't have the heart to tell him that there was an easy way to do what he wanted (nor did I tell him that the Pen Tool would probably be much better for his needs).

When you're making your selection and you get close to the edge of the document window, all you need to do is hold down the Spacebar (without letting up off the mouse button, of course). The Hand Tool will do its duty moving your view around, and when you let go of the Spacebar, your selection is still intact and you can continue with your Lasso selection.

As a side note, using the Marquee Tool to make a selection, and halfway through, hold the Spacebar down while moving the mouse. Then let go of the Spacebar and continue making your selection. See what just happened? Believe it or not, I actually had a use for that feature, maybe someday you will too.
