Where are pointing arrows located in dashboard studios

[OgoNARA]

Might be a silly question but does anyone possibly know where I can locate lines with pointing arrows at the end? I wanted to use them to point to each panel I had to show a flow diagram of some sort.

Arrows are an attribute of lines.  They don't show up, however, until you increase the thickness of the line.
