Unfortunately, although there is a large overlap between menu
operations and commands, there is not a 1-to-1 relationship, and
sometimes the mapping is not obvious. Some things can only be done in
menus or GUIs, some only with commands. A brief historical perspective:
as Chimera was created, many commands from Midas were reimplemented in
the new framework. Midas was almost completely command-driven. As
Chimera has been developed further, the Select and Actions menus and
many new tools with complex GUIs have been added. Some but not all of
these new tools have also been implemented as new commands.
will hide all the atoms and bonds, but there is no command for changing
to the orthographic projection.
If you (and other users out there) need particular operations to be
available as commands, let us know, and that will be factored in as we
Here are some ideas for figuring out correspondences, in order of
decreasing efficiency (in my opinion):
(a) see the Chimera Commands Index
or the Chimera Quick Reference (PDF file)
which give brief explanations of what each command does; then you can
look at the detailed man page for a command if it sounds like what you
(b) There is some degree of cross-referencing in the User's Guide; for
example, the Actions menu listing includes several "see also command"
The two beginner tutorials go through mostly the same tasks, one using
the menu, the other using commands. However, it sounds like you are
beyond the beginner stage, and it might not be convenient to put up the
two tutorials in side-by-side browser windows.
(c) you can search for topics of interest with Help... Search
Documentation. The hits will generally include some command man pages.
I hope this helps,
