TITLE           LOGICAL ZOOM MODE

OCCURRENCE      ARB_NT and ARB_PARSIMONY: <LZoom> button in the left column
                F5 on the keyboard

DESCRIPTION     The 'LOGICAL ZOOM MODE' allows you to display subtrees within
                the tree display area of the 'ARB_NT' window.

                Click on the <LZoom> button of the 'ARB_NT' window or press the
                        'F5' key on the keyboard to activate the 'LOGICAL ZOOM
                        MODE'. In the latter case, the cursor has to be placed
                        within the tree display area.

                Display a subtree:

                        Move the cursor to that internal node of the displayed
                        tree (section) which defines the subtree and click on
                        the left mouse button. The subtree-defining node is that
                        located closest to the indicated root (open square)
                        of the whole tree which directly or indirectly connects
                        all branches of the subtree.



NOTES           To reset the display to show the whole tree either
                - choose the 'Logical Zoom' item from the 'Tree/Reset zoom' menu or
                - left-click somewhere outside the tree or
                - press the key '0' (zero) in the tree display.
