argument list for ArrowBox?
I'm using Mathematica 7.0.1 on a Mac (OS X) to prepare an exam for a basic physics lab. This often calls for a Graphics cell to depict some configuration. Since this cell is invariably created square, and there seems to be no easy way to change the box's aspect ratio within Mathematica, I open a text editor and edit the exam's .nb file directly, modifying the options of ImageSize. This is awkward, but works. In the process I ran into the function ArrowBox, whose options I'd like to modify to eliminate an invisible mask that's cropping the arrowhead. But I've been unable to find anywhere a description of ArrowBox's arguments. The instruction Options[ArrowBox] produces an empty pair of curly brackets. All I've gathered so far is that the arguments consist of a two-component list of two-component lists of numbers. How do I find that sort of information? Thanks. - Dushan Mitrovich
