TITLE		SPREAD MODE

OCCURRENCE	ARB main window <button in the left column>

DESCRIPTION	The 'SPREAD MODE' allows you to increase or decrease the angles of
		adjacent terminal branches or all angles within subtrees.

		Click on the tenth button in the left column of the
                ARB main window to activate the 'SPREAD MODE'.

		To spread all angles of a subtree, click and drag a branch
                towards the tips of the tree.

                To reduce the angles, drag towards the tree center.

                To reset the spreading of a subtree to the default value,
                press the key '0' (zero) while pointing to that subtree.

                To reset the spreading of the whole tree, point somewhere outside
                the tree while pressing zero.

                See also LINK{mode_rotate.hlp}.
