420 Chapter 38:
Detail Editing Segments and Points of Vector Objects
Bend Segments modifies an existing curve and any curves attached to it.
Bend Segments changes a line to a curve then modifies the flex of the new curve.
If the Retain command is turned off when using the Move tool, the segment is separated from
the original object, creating two open objects. When Retain is off, the other three Property Bar
options are unavailable.
Retain Off disconnects the segment from the rest of the shape.
You can also move segments (or points) using the keyboard arrow keys (Nudge). Select one or
more segments and move one pixel for each press of an arrow key. Use Shift + arrow keys for a
Super Nudge move. Super Nudge distance is set on the Detail tab of Tools > Options.
