## 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_NT' 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 ´ROTATE MODE´.
