Hi Alexis, At least without the spec part, you can do it with command (if you don’t mind losing any current selection): sel ##display; hide sel models; show ~sel models; ~sel If you really need the spec part, you could make an alias, e.g. in your startup commands (see Preferences) <http://rbvi.ucsf.edu/chimerax/docs/user/preferences.html> <http://rbvi.ucsf.edu/chimerax/docs/user/commands/alias.html> alias toggle sel ##display; hide sel models; show ~sel models; ~sel alias stoggle sel ##display; hide sel & $1 models; show ~sel & $1 models; ~sel <http://rbvi.ucsf.edu/chimerax/docs/user/commands/alias.html> <http://rbvi.ucsf.edu/chimerax/docs/user/commands/atomspec.html#attributes> … then in ChimeraX you could use toggle — or if you want to use a specifier — stoggle <spec> The <spec> could not be selection-based (e.g. “sel”), however.

Hello, Apologies if this already exists, but I'd like to suggest a new option to the show/hide command:

show spec toggle

which would behave like the toggle option of volume (one of my favorite chimeraX features by far), but would work on atomic models. Within the spec, anything currently shown would become hidden, and vice versa. Cheers, Alexis
