You guessed correctly, you may add nodes and link them to build brand new programs and improve existing ones.
Let’s extend our counting program so that we’ll have two independent counters.
clocknode will appear where you have double-clicked.
INCpin by clicking on one pin, then the other.
count's output pin and
watch's input pin.
Run the simulation to see how the counters work in parallel. Try to set different
IVAL parameters and see how it changes the behavior.
Alternatively to double-clicking you can also press the “I” key or hit Edit → Add Node.
If you don’t remember the name of a node, try to find it in Project Browser. Once you spot it there, drag’n’drop the item to the patch board or hit Place in its context menu.
Another way of duplicating a group of nodes and links is selecting them by drawing a frame around to select multiple nodes at once and then copy/paste using the Edit menu or keyboard shortcuts traditional for your OS.
If you draw the selection frame from left to right, a node is selected only if fits inside completely; if you draw from right to left, the nodes which intersect the frame are also selected.
