this is _not_ a VMD tutorial, but the user's guide. please
have a closer look at the VMD homepage to find real tutorials.

please note, that you are referring to 'subcommands' to procedures
created by the atomselect command. some of those are implemented as
vmd_atomselect_XXX() procedures, but that is the exception rather
than the rule (as it makes only sense for subcommands that are wrappers
to other subcommands). this is very much related to the way atomselect
is implemented and how VMD in general handles some of its functionality.

perhaps, it might be more useful if you describe, what you are
planning to do with VMD and people here can give you some
recommendations on tutorials or equivalent that can help you
better than just reading the user's guide.

what version of VMD do you have? i cannot find this file in the
recent version.

all functionality described in the VMD user's guide is contained
in the VMD distribution. what is not in a tcl file is implemented
in c++ (or in python). if you are after tcl scripts with useful
functionality, please have a look at the VMD script library.
