[Chimera-users] ~select doesn't work on axes?

Thanks Elaine, tricky! And very helpful, thank you - one of my aliases was breaking when I ran it with axes or planes selected, this fixed it.
So I now have the following aliases for hiding/showing selected axes (unselects everything that is not an axis first, then hides/shows using modeldisp):
#hide selected axes
alias ^hide_axis ~sel; ~modeldisp sel
#show selected axes
alias ^show_axis ~sel; modeldisp sel

As we added more and more functionality, other types of objects (nonmolecular surfaces, etc.) were shoe-horned into working with certain commands, but these are more the exception than the rule. For example, distance and angle commands can take axis/plane/centroid identifiers, but most other commands do not…

You can re-show the objects with “modeldisp sel” or all models with just “modeldisp” … this command works on whole models, even the nonatomic ones. It doesn’t know about object identifiers (a1, p1, etc.) so you can only use it with “sel” to indicate specific axes/planes/centroids.

I can only figure out how to do so from the GUI but I would like to do this from the command line, as when you have many axes defined and only want to hide a few it would be easier to have an equivalent of “~disp sel” rather than hunting for the specific axes in the Axes/Planes/Centroids list.
