User Guide

In the Outline Window the arrow keys will move selected
points by ten em units in the direction of the arrows. If the
default setting in Preferences is changed, then this number
will reflect that change.
Option (Caps Lock)-arrow moves selected points by one
em unit in the direction of the arrow. When the default
setting in Preferences changes this number will be 1/10th
the distance of the new setting.
Shift-arrows move the selected points in the direction of the
arrows by 10 times the default setting.
In the Metrics Window, use the left-right arrow keys to
move to the next or previous character in the screen
display when a character is selected.
