TITLE           ZOOM MODE

OCCURRENCE      ARB_NT and ARB_PARSIMONY: <PZoom> button in the left column
                F4 on the keyboard

DESCRIPTION     The 'ZOOM MODE' allows you to magnify selected square sections of
                the tree display area within the main window.

                Click on the <PZoom> button of the main window or press
                        the 'F4' key on the keyboard to activate the 'ZOOM
                        MODE'. In the latter case, the cursor has to be placed
                        within the tree display area.

                Define and magnify a section:

                        Position the cursor to define the first corner of the
                        square to magnify. Keep the left mouse button pressed
                        and move the cursor to define size and position of the
                        region to magnify. Release the button.

                Increase/reduce the zoom scale:

                        To gradually increase or reduce the zoom scale click the
                        left or right mouse button while the cursor is located within the
                        tree display area of the 'ARB_NT' window.

                        Alternatively you may use CTRL+Mouse-Wheel (this works independent
                        of the currenly select mode).

NOTES           To restore the initial zoom either
                - choose the 'Physical zoom' item from the 'Tree/Reset zoom' menu of the 'ARB_NT' window or
                - press the key '0' (zero) in the tree display.
