Chapter 4: Display
4-4: Zooming and Panning
4-4-3: Focus

A particular scale and pan in a window is called a focus. Each time you zoom in or out, the focus is saved in a list.

You can move back through the list and show the last focus with the Go To Previous Focus command (in menu Windows). You can move forward in the list with the Go To Next Focus command.

The Set Focus... command (in menu Window) lets you type specific pan and zoom factors. The "X Center" and "Y Center" fields are the database coordinates of the center of the screen. The "Horizontal Grid Units" field is the number of database grid units across the screen.
