A short descriptions of each 'MODE' is shown directly above the tree display subwindow. It informs about the differences between the left and right mouse key and tells if there are mode-specific keyboard shortcuts available.
To execute the respective functions, the cursor has to be located within the tree display area while pressing the mouse buttons.
The scale bar and its label can be moved by positioning the cursor anywhere on the bar, keeping the left mouse button pressed, moving the cursor to the desired position and subsequently releasing the mouse button. The label of the bar can be moved independently.
