[chimerax-users] setting up mousemode - translate z - set pivot

[Helge Paternoga]

Hi Elaine and Tom,

Thanks for the explanations, that was very helpful. The build-in shift 
functionality indeed explains the translate/rotate behaviour!

For me the shift button + "reversed" translate/rotate functions work 
perfectly, so I guess I will keep it that way. Is there anything else 
that speaks against it?

For fitting, I am dealing with ribosomes and I have come to align the 
map I am fitting into in a way that makes the features clearly 
distinguishable (i. e. the straight solvent side of the large subunit 
viewed from the side), then I just move in my new map rotate to align 
the features and dump it using the z translate until it is in the other 
map, followed by fit in map.

I was contemplating on how much I should stick to my old habits vs. 
trying new behaviours that might be more effcient in the long run. It is 
clear that ChimeraX offers many new opportunities for improving the 
workflow, but for now I like to keep my old logic (which cleary comes 
from using Chimera for a long time). I like to have three separate keys 
for rotating - xy translating - z translate that can be modified for the 
selected model (or dragged, will look into that). Therefore, I came up 
with the following setup:

mousemode shift leftMode 'translate selected models'
mousemode shift middleMode 'rotate selected models'
mousemode shift wheel contour
mousemode setting contour speed 0.1
mousemode control wheel 'translate selected models'
mousemode setting zoom speed -1

This actually leaves the right mouse button completely free and I was 
already wondering what could be a good function to map here!

An unrelated observation that I had was that with grey background the 
selection rectangle while holding control is not visible on the 
background anymore (It works with white and black).
