Use the Tab key to move from box to box in a window.
There are three ways to change a number in a box.
Place the cursor over the word next to the box in the options bar, such as Zoom.
The cursor will change to a finger with two arrows.
This is called a scrubby slider.
Click and hold, and move your mouse to the left and right, to change the value in the box.
If you hold down Shift, the value in the box changes by an increment of ten.
If you hold down Alt, the numbers change very slowly.
If there's no text next to the box, press and hold Ctrl.
Then, move the cursor over the box.
Click the word next to the box in the options bar.
The box will become highlighted.
Then, do one of the following.
• Enter a new value in the box.
• Use your mouse scroll wheel to change the value in the box.
If you hold down Shift, the percentage changes by a increment of ten.
• Use the up-and-down arrow keys to change the value in the box.
If you hold down Shift, the value in the box changes by an increment of ten.
Click the arrow next to the box.
A slider will appear below the box.
Then, do one of the following.
• Click on the pointer on the slider, hold, and drag the pointer along the slider.
• Click on the pointer on the slider, and change the value in the box by using the arrow keys.
To change by an increment of ten, hold Shift down.
