Improve documentation for using Measure Tool to measure angles.
Operating System: general (tested on Mac)
Description of the feature
The documentation says "Holding down the Shift allows to start a new measure from the pointed point without deleting the previous measure."
It took me a whole lot of experimentation to determine that the behavior is more like:
"While holding down the Shift key, click and drag from an existing endpoint to create a second measurement line from this endpoint. The angle between the two lines will be displayed. Any endpoint can be moved by clicking and dragging."
I suggest changing the documentation text to something like the above text.
The existing text omits two key things: You must click and drag while holding down Shift, and you must start at an existing endpoint. Without knowing these two tricks, the previous line is deleted, contrary to the documentation.
