CUSTOMISE THE CONTROL STRIP
How to work with System 7’s equivalent of menu bar icons
1 What is the Control Strip?
Introduced with System 7, the Control Strip provides quick access to some of the more common system settings, such as turning AppleTalk networking on or off, checking battery status, or adjusting the system volume. It sits at the bottom of the screen, like the Dock, but functions more like the menu bar icons in OS X.
2 Adjust its position
You can reposition the Control Strip by dragging it up or down the left- or right-hand side of the screen. If you want to hide it, you can click the little square icon at the left of the strip, but this leaves behind the bevelled handle as a reminder. To get rid of it completely, choose > Control Panels > Control Strip.
3 Customise its controls
On a PowerBook, the two most useful Control Strip functions are the one that puts the laptop to sleep and the one that spins down the very noisy hard disk. You can customise the Control Strip to show just these by dragging the icons to the far left of the list, then dragging the sizing handle back to hide the others.
