Go: Click Go to jump to the view you select from the Navigator or in the Overview.
Note: Clicking Go is the equivalent of double-clicking one item on the Navigator tree view or double-clicking on the Overview inside the frame of the Overview.
Zoom Out: Clicking this results in reduction on the visible plan in the overview area.
Zoom: Sets the zoom on the plan visible in the overview area.
Zoom In: Clicking this results in magnification on the visible plan in the overview area.
Zoom Pop-up Menu: You can define the connection between the Navigator Preview and the frontmost window. You can also redraw preview from here.
Real-time Zoom: If you choose this option, the zooming and panning operations made in the preview are continuously shown in the window.
Auto zoom: With this option, the zooming and panning operations made in the preview do not affect the screen display until you release the mouse button.
Double-click to zoom: With this option, the view does not reflect the display changes made in the preview. To update it, you need to either double-click inside the preview or click the Go button in the top right corner of the palette.
Redraw Preview: This command updates the preview window if you have edited the contents of the active window.
