The zoom in tool, found in the editor
toolbar, provides a way to zoom in and re-center (pan) the image in
the work area. When this command is
activated, clicking in the work area will cause the work area view to
zoom in and re-center on the point picked. This will continue until
a ~11’ x 11’ area (~3m x 3m if working in metric
units) is displayed. Use the zoom in tool in combination with the
scroll bars to the right and at the bottom
of the work area to adjust the view. The cursor will change to a
magnifying glass with a + symbol to let you know that the current
edit mode is set to zoom in.
To zoom into a specified window, select the first zoom point and drag the cursor to another point. A transparent window will identify the area about to be displayed.

You can also zoom to a percentage of the normal view by selecting a value from the zoom % list at the bottom of the work area. You can also enter a number in the zoom % box to zoom to that level.
Note: You can also invoke a zoom in command in the middle of another action by pressing the [Ctrl] and [+] keys simultaneously.
