This one is pretty simple, but very easy to overlook. When using Photoshop, especially on small laptop screens, the cursor often just seems to "vanish" into thin air -- this is possibly due to LCD screen redraw lag, or just because the 'accurate' form of the various cursor types tend to be very small. So, when trying to position the cursor accurately, just hold down the Space Bar for a second, and the cursor, wherever it is on the screen, will switch to a relatively large 'hand' icon. That's usually enough of a visual hint to be able to reposition it to where you want it, so you can switch to another tool, crop, marquee, or brush, and get on with your work. This sure saves on eyestrain -- and that's a good thing!
