Symbols for Image Annotation
The 2dlabels command
allows adding 2D text and symbols to the display.
Symbols and special characters can be incorporated by copying
(such as from this page) and pasting them into the command.
They can also be incorporated into
Color Key labels and
the “3D” (atom-associated) labels shown with
the label command.

Whether a given symbol is rendered properly in this page depends on
the web browser and display font, and whether it is rendered properly
in ChimeraX depends on the system and label font typeface.
The arrow symbols in this page can only be drawn in the orientations shown.
