Zooming
Located in the 
toolbar are the usual methods for zooming, which function the same in all views.
· Zoom rectangle
· Zoom in
· Zoom out
· Show all
Additionally, there is the function ‘Zoom to Cursor’. With this function zooming takes place directly at the cursor position using the mouse wheel, if the key combination ‘Ctrl+Shift’ is kept pressed.
‘Ctrl+mouse wheel’ results in ‘Zoom in’ or ‘Zoom out’, depending on the direction in which the mouse wheel is turned.
