Zooming Into The Layout

Select the zoom area with the right mouse button in the layout canvas.

Press the button, drag the box to the desired position and release the button.

To zoom in (enlarge) drag the box right and down. To zoom out (shrink) drag the box up and left. To choose a new center, single-click the new center point with the right mouse button.

Additionally, these functions are available from the menu or by hotkeys:

Pan to the left, right, top or bottom using the arrow keys or choosing one of these functions from the "Display" menu.
Fill the whole selected cell into the window by pressing "F2" or choosing "Zoom Fit" from the "Display" menu
Zoom in or out by a fixed amount by pressing "Enter" or "Shift+Enter" or choosing "Zoom In" or "Zoom Out" from the "Display" menu
Zoom in and out by using the mouse wheel if available. The current mouse location will stay fixed, while the surrounding layout will be enlarged or reduced in size
Press "Shift" while dragging the mouse with the right mouse button pressed will drag the layout similar to what happens in recent map service web applications
