Pressing the CTRL key while the wiring tool is active near a dual input arithmetic operation will change the mouse icon as shown below. Left-clicking will switch the wires.

Here’s a tip I stumbled onto because I was too slow on the keyboard and did two things at once. If your mouse is inside the case structure (for example, as shown below) and you hold down the CTRL key, then the mouse wheel will advance you through the frames (frontward or backward depending on the wheel direction). This method is much faster than arrow usage and, except for deep case levels, such as in a state machine, it is faster than using the case select pull-down menu.

Want another tip on usage? Put your mouse near a corner before you start cycling, because if one of the cases also contains a case structure, you might get stuck in cycling through the internal case.

When opening subVIs during coding, you usually want to see the block diagram of the subVI. But, double-clicking on the subVI opens the front panel which you usually follow by CTRL-E or the ‘Window>>Show Block Diagram’ menu item.

A better way is holding down the CTRL key while double-clicking. This opens both the panel and the diagram with the diagram on top.
