Outside of AcadE -
Locate your wd.env file (on a standalone install it will be something like \My Documents\Acade {version}\AeData).
Open it with a text editor like Notepad.
Look for lines like this -
*SETQ:GBL_wd_xref_mtext_pinfont,"romans.shx",graphical cross-references - font for the "terminal pin" text
*SETQ:GBL_wd_xref_mtext_pinsize,"0.67",ratio pin/reference text size
Remove the initial "*" which comments the lines out. Then put in the font and size you want. Restart AcadE.
This has been in AcadE for a long time but no UI was added for defining this so it is pretty hidden.
