The examples above show a set of commonly used arrow shapes. There is a grammar of arrow shapes which can be used to describe a collection of 3,111,696 arrow combinations of the 42 variations of the primitive set of 11 arrows.

The basic arrows shown above contain:

• most of the primitive shapes (box, crow, diamond, dot, inv, none, normal, tee, vee)
• shapes that can be derived from the grammar (odot, invdot, invodot, obox, odiamond)
• shapes supported as special cases for backward-compatibility (ediamond, open, halfopen, empty, invempty).
