You can use the Zoom slider to quickly zoom in or out of the view or drawing sheet without having to click a zoom command. The Zoom slider zooms dynamically or by steps.
Zoom in using the right side of the slider bar or the plus button .
Zoom out using the left side of the slider bar or the minus button .
When the slider is in the middle, the view is fit to the window.
If you have graphics selected when you use the slider, then it will zoom about the center of the graphics. Otherwise, it will use the center of the active window.
Note:
You can remove the Zoom slider from the status bar using the Customize Status Bar command on the status bar shortcut menu.
