Here's the list of keys recognized by ARB_NTREE:
Key Description
==========================================
m mark/unmark (sub-)tree
i invert marks of (sub-)tree
x expand (Unmarked,All)
c collapse (Terminal,All)
If you point on a subtree while pressing one of the keys, the action is performed on the subtree. Otherwise (if you point somewhere outside of the tree) the whole tree is targeted.
If you press < SHIFT + Key > the function works on the opposite set:-
Instead of the subtree, the rest of the tree is targeted.
-
Instead of the whole tree, all species NOT in tree are targeted.
If you press < CTRL + Key > the function works on ALL species (if it makes sense).
