The following bug report has been submitted:
Platform:        Darwin-19.5.0-x86_64-i386-64bit
ChimeraX Version: 1.0 (2020-06-04 23:15:07 UTC)
Description
help command does not show documentation in browser for abbreviated commands if they have only subcommands.  For instance,

help measur
-> shows usage

help measure
-> shows help browser.

There are many commands with only subcommands.  These should show the help browser even when the command is abbreviated.
