The implementation part of the graphical editors for FBD, LD, CFC, and SFC contains a toolbar in the lower right corner:

Return to normal editing mode

The mouse pointer changes back to the shape of the default arrow. You can select and edit elements in the editor view.

Panning tool

The mouse pointer changes to the shape of two crossed arrows. You can click and drag anywhere in the editor view to move the visible area of the FBD/LD editor or also pivot a CFC chart.

Magnification tool

A magnified window opens in the lower right corner of the editor view and the mouse pointer changes to the shape of a cross. As you move the mouse pointer over your diagram, the magnification tool shows the area of the diagram below the cross at 100% magnification. Note: When you click in the view, the magnification tool closes and the part of the diagram which the tool contained is displayed at 100% magnification. If you want to keep the set zoom factor, then you should use to return to the default editing mode.

Zooming tool

This opens a list box with a selection of zoom factors. Clicking more selections (‎...‎) will open the “Zoom” dialog for typing other values. The current zoom factor is always displayed to the left of the symbol.
