You enter values using the same methods in all panels and dialog boxes. You can also perform simple math in any box that accepts numeric values. For example, if you want to move a selected object 3 units to the right using the current measurement units, you don’t have to work out the new horizontal position—simply type +3 after the current value in the Transform panel.
Type a value in the box, and press Enter or Return.
Drag the slider.
Drag the dial.
Click the arrow buttons in the panel to increase or decrease the value.
Click in the box and then use the Up Arrow key and Down Arrow key on the keyboard to increase or decrease the value. Hold down Shift and click an arrow key to magnify the increase rate or decrease rate.
Select a value from the menu associated with the box.
