The 'MARK MODE' allows you to mark and unmark individual species, or all
species of a subtree.
Click on the <MARK> button (first button in the left column) of
the 'ARB_NT' window or the 'F2' key on the keyboard to
activate the 'MARK MODE'. In the latter case, the cursor
has to be placed within the tree display area.
Mark single species:
Move the cursor to any terminal branch or the left part
of the information displayed at the terminal node and
press the left mouse button.
Mark all species of a subtree:
-
Move the cursor to any position along the edge defining
the subtree and proceed as described above.
-
The subtree-defining branch is that located closest to
the indicated root (open square) of the whole tree
directly or indirectly connected to all branches of the
subtree.
