protecting properties in proxy

Hi all,

The Blender manual says you can protect things for proxies using Ctrl-Leftclick. Unfortunately this does not work. The documentation is still from 2.4x, and I did not find newer information.

For bone layers, it seems to work fine using the “protected” buttons (though ctrl-leftclick does not seem to do anything different from a usual leftclick, in contrary to the manual’s informations(?))

…but what about other properties, like the material or object’s transform?

Anyone tried this and succeded?

Best greetings, Michael
