The tree walking commands
are summarized in Table 
.
UP, LEFT, RIGHT, DOWN-LEFT, DOWN-RIGHT are the basic walking commands. Within text slots, LEFT and RIGHT stop at each word. (Use screen motion commands to move by character.) These commands recognize text and term sequences, and skip over their internal structure.
RIGHT-LEAF, LEFT-LEAF, RIGHT-EMPTY-SLOT, LEFT-EMPTY-SLOT are
particularly good for rapidly moving around terms, since you can often get
where you want to go by just repeatedly using one of them. Note
that the binding of
RETURN
to RIGHT-EMPTY-SLOT doesn't work
in text sequences. In that case, you need to use 
C- RETURN 
.
