Toolbar Buttons

The toolbar contains the following tools, which you can use to run and edit a VI.

Run runs a VI. LabVIEW compiles the VI, if necessary. You can run a VI if the Run button appears as a solid white arrow, shown at left. The solid white arrow also indicates you can use the VI as a subVI if you create a connector pane for the VI.
While the VI runs, the Run button appears as shown at left if it is a top-level VI, meaning it has no callers and therefore is not a subVI.
If the VI that is running is a subVI, the Run button appears as shown at left.
The Run button often appears broken, shown at left, when you create or edit a VI. If it is still broken when you finish wiring the block diagram, the VI is broken and will not run.
Run Continuously runs the VI until you abort or pause execution.
Abort Execution aborts execution of the top-level VI. If more than one running top-level VI uses the VI, the button is dimmed. You also can use the Abort VI method to abort the execution of the VI programmatically.
Note  Avoid using the Abort Execution button to stop a VI. Either let the VI complete its data flow or design a method to stop the VI programmatically. By doing so, the VI is at a known state. For example, place a button on the front panel that stops the VI when you click it.
Pause pauses execution. When you click the Pause button, LabVIEW highlights on the block diagram the location where you paused execution. Click it again to continue running the VI.
Enter appears to remind you that a new value is available to replace an old value. The Enter button disappears when you press the <Enter> key, click the front panel or block diagram workspace, or click the Enter button.
Highlight Execution displays an animation of the execution of the block diagram.
Step Into opens a node and pauses. When you click the Step Into button again, it executes the first action and pauses at the next action of the subVI or structure. You also can press <Ctrl> and the down arrow key.

Macintosh Press <Command> and the down arrow key.

Sun Press <Meta> and the down arrow key.

Linux Press <Alt> and the down arrow key.

Step Over executes a node and pauses at the next node. You also can press <Ctrl> and the right arrow key.

Macintosh Press <Command> and the right arrow key.

Sun Press <Meta> and the right arrow key.

Linux Press <Alt> and the right arrow key.

Step Out finishes executing the current node and pauses. When the VI finishes executing, the Step Out button becomes dimmed. You also can press <Ctrl> and the up arrow key.

Macintosh Press <Command> and the up arrow key.

Sun Press <Meta> and the up arrow key.

Linux Press <Alt> and the up arrow key.

Text Settings changes the font settings for the VI.
Align Objects aligns objects along axes.
Distribute Objects spaces objects evenly.
Reorder moves objects relative to each other. Select the Reorder pull-down menu when you have objects that overlap each other and you want to define which one is in front or back of another.
Warning appears if a VI includes a warning and you placed a checkmark in the Show Warnings checkbox in the Error List window.
