Hints are displayed in many places to help you use the tools. These hints open automatically.

You can close this help again by

• selecting the close symbol (the 'x' in the top right corner) or
• making a hand gesture

The hand gesture is a quick movement with the right hand that returns to its origin. When you make a gesture, this is indicated by two straight lines forming an angle.

The gesture is recognised when the angle formed by the straight lines is acute. You will then see green lines and the help will be opened or, if it was already open, closed again. If you see green lines and no help appears, then there is currently no help page available.

If you see red lines, the hand gesture has not been recognised because the angle is too obtuse.
