When the right button is set to make selections,
and one right clicks outside the selection,
then the right click menu opens.
1. tools > settings > keyboard/mouse: right button: make selection
2. draw a selection on an image
3. right click outside the selection
the selection is removed (expected)
the right click menu opens (unexpected)
If the right button is set to "make selection",
and there is a selection on the image,
On the selection:
open the right click menu.
Outside the selection:
remove the selection,
do not open the right click menu.
If there is no selection on the image,
should open the right click menu.
It might also be a good idea to add Crop to the
right click menu when there is a selection on an image,
this applies to both when the left or right button is used for selecting.
