2. Click and hold down the left mouse button while pointing to the up arrow of the Width
spinner. Notice that the box continues to grow in width as you hold down the mouse but-
ton. When you hold the mouse button down and move the mouse forward or backward,
the rate of change on the values is accelerated.
3. Right-click the spinner arrow. The box shrinks in width to 0. Right-clicking any
spinner changes the spinner value to its lowest possible non-negative value, which is
0´0.0˝ in this case.
4. Click on the Width spinner and drag the mouse up. The box grows wider. Click and drag
down, and the width decreases.
5. Click and drag the Width spinner up until the cursor reaches the top of the screen. Then
continue moving the mouse up the screen, and notice that the cursor reappears at the bot-
tom of the screen and continues moving up the screen. This circular action of the spinner
lets you scroll continuously without being limited by the screen area.
Undoing Spinner Changes
While adjusting a spinner, you can immediately undo any changes you make by right-clicking the
mouse while still holding the left mouse button. This allows you to quickly experiment with spin-
ner settings while you work.
You’ve just seen how you can change the parameters of an object by using the spinner. Now
let’s take a look at the absolute way of entering values into input boxes.
1. Double-click the Length input box in the Parameters rollout and type 60↵. Notice how
the box’s length changes and the Length value changes to 5´0.0˝, the feet and inches
equivalent of 60˝.
Notice that it’s not necessary to enter the inch (˝) symbol to indicate a measurement in inches.
You are, however, required to enter the foot (´) symbol when entering a measurement in feet.
This is because you selected the Inches option as the default units in the Units Setup dialog
box earlier in the chapter.
2. Press the Tab key. Notice that the Width value is now highlighted.
3. Type 60↵ for the width and press Tab again. The Height value is highlighted.
4. This time enter 5´↵. The box is now a cube 60˝ square.
