Navigating the Basic panel via the keyboard
You can use the and keys (or you could refer to these as the and keys) to cycle backward or forward through the Basic panel settings, making each in turn active. When a setting is selected, you can use the and keys to increase or decrease the unit settings. Holding down the key when tapping the / keys uses larger increments, while holding down the key uses smaller increments. As you do this you’ll also see an overlay appear in the content area indicating the adjustments being made (see Figure 4.34).
Figure 4.34 This shows the overlay that appears as you use keyboard shortcuts to edit the Basic panel settings.
Figure 4.35 The Basic panel adjustments shown here were all achieved by clicking on different sections of the histogram and dragging right or left to increase or decrease the setting represented by that particular section of the histogram. You can also double-click on these areas of the histogram to reset the values.
