Adjusting the Shelf for a Shelf Control
When you add a shelf control such as a keyboard to the workspace, it appears at a default
angle, creating a three-dimensional appearance. You can adjust the angle of the shelf
control so that it appears more or less three-dimensional. This can be useful, for example,
if you want to see more of the keys on the keyboard or minimize the amount of space it
occupies onscreen.
To adjust the angle of the shelf for a shelf control
1 In the workspace, select the shelf control.
White alignment guides for the control’s shelf appear.
Alignment guides
2 Drag the lower alignment guide (the one aligned with the front of the shelf control).
Drag the lower alignment guide down to make the angle steeper (as though you are
looking down on the shelf control from above), or drag it up to make the angle less steep
(as though you are looking at it from the front).
Drag the front (lower)
alignment guide to change
the angle of the shelf.
