The two finger zoom (multi touch) of some smartphones can also be used. The map can be dragged via a touch into a certain direction (pan). If the mobile client is used in a desktop browser, you can pan via the right mouse button.
Note: Multi touch is supported for Android from version 4.x and iOS.
If the WebOffice mobile client is used on a desktop, a zoom via bounding box is possible with the following shortcuts:
•Zoom In: Hold Shift + draw a bounding box
•Zoom Out: Hold Ctrl + draw a bounding box
