Method of Controlling the Tracing of a Logic Network

      Disclosed is a method of tracing a network in a simple,
friendly, and intuitive manner using cursor control keys.

      To monitor or debug problems in networks, the network is often
presented graphically on a display.  A user then enters commands to
show portions of the network that did not fit on the display screen,
or to select a certain node for a later action.

      This invention uses the arrow cursor control keys to perform
this selection.  The left arrow key causes all inputs to a node to be
dis played or selected.  The right arrow causes all outputs of a node
to be displayed or selected.  The up and down arrow keys causes each
of the inputs or outputs (depending on which were previously selected
by the left and right arrow keys) plus the primary node to be
scrolled through.  Once a particular input or output is selected via
the up and down arrow keys, the left arrow key will trace backward to
the node driving this input or output, and the right arrow key will
trace forward to the node being driven by this input or output.  In
other words, the up and down arrow keys allow selection of a
particular input to or output from the current node, while the left
and right arrow keys allow selection of a new node or causes inputs
or outputs to be displayed or selected.  Usage of the arrow keys is
very intuitive, in that the left arrow key causes selection of
driving nodes, which are usually repres...
