Scrubby Sliders

In all Adobe programs scrubby sliders let you have the option of setting a value or dragging a slider without having to actually grab the slider. Simply place your mouse over the name of the value (for instance the Opacity value in the Layers palette), click and drag from left to right to set the value. This works with most values, not all, and is really a great time saver if you get the hang of it. You can also hold SHIFT while dragging to set the value by ten.

And a related tip: To set the value of a setting using the keyboard simply click the name to highlight it (or click the number), and use the up & down arrows on your keyboard to increment the value up and down. Hold SHIFT to increment values by ten.
