Drawing Signals 21
above, the mouse button does not have to be held down while creating sig-
nals in this mode. Double-clicking terminates the signal line.
Editing a Signal Line
The following features are available to edit signal lines:
 Zap mode (entered by selecting the Zap command in the Edit menu or
the Zap item in the Tool Palette) allows you to remove any single line
segment from a signal connection. Zapping on a signal line removes
only the line segment to which you are pointing—up to the nearest
intersection, device pin, or segment join point.
 Selecting a signal line (by clicking anywhere along its length), then
hitting the key or selecting the Clear command from the Edit
menu, removes an entire signal trace.
 Drawing backwards along the length of an existing line causes the line
to be shortened to end at the point where you let the button go.
 Clicking and dragging the middle of a signal line segment allows you
to reposition the line. Vertical lines can be moved horizontally and vice
versa.
Checking Signal Interconnection
Double-clicking anywhere along a signal line will cause that signal seg-
ment and all logically connected segments to be selected.
