Hi Alexis, Sounds like the problem is solved.

Aside from the ISOLDE override, your "mousemode" commands do look correct. Also I believe that simply assigning "select" to a new button will automatically make the addition of Shift to that assignment into "select toggle" (add if not yet selected, subtract if already selected).

For example, assigning right-mouse to "select" then changes Shift-right-mouse to toggle selection, without my having to explicitly assign it.

However, that only works if the assignment of Shift + the "select" button(s) is "none"... if you assigned it to something else, it won't automatically toggle select.

Hi Tristan,

I think you hit the nail on the head. I should have tried to reproduce this with a simpler setup with a single model before asking for help! This is the first time I am working with a multi-model setup (single PDB, multiple models), and indeed this is what threw me off.

So I think I will manipulate my PDB to have everything in a single model - will make my life easier I think.

I guess it would be nicer if mousemode worked as expected... but I can see how that might be tricky if the user selects outside of the model ISOLDE's currently dealing with.

Thanks! Alexis

• an approach that made sense at the time (around 2 years ago)... now that things are more mature perhaps it’s time I looked at making ISOLDE play nicely with the default select mode.

Hi all,

Not sure whether this is a ChimeraX question, or an ISOLDE question, or a bit of both.

I am using ChimeraX 1.0 (2020-06-04) and ISOLDE version ChimeraX_ISOLDE-1.0.1-cp37-cp37m-macosx_10_13_x86_64.whl.

When I start ChimeraX, I get the following left mouse bindings, which I believe are default:

• ctrl-left click = select
• shift-ctrl-left click = select add

When I just start ISOLDE via the GUI menu (no further action), this seems to clear the mousemode. Or, at least, ctrl-click does not select anymore, and shift-ctrl-click also doesn't seem to do anything.

To remedy this, I issue the following commands: mousemode control left select mousemode control shift left 'select add'

This restores ctrl-left to 'select' as expected, but shift-ctrl-left also triggers 'select', not 'select add'.

Couple of questions: (1) Is ISOLDE intentionally overriding mousemode when it is launched? I'm 99.9% this didn't use to be the case pre-1.0... (2) How do I restore shift-ctrl-left to 'select add'? I assume I am getting the syntax wrong, but I did read the doc and thought I was following it, so I guess I need some help understanding the syntax.

Cheers, Alexis
