Dear all, It's perplexing for newbie users that Chimera does not react to the basic keyboard shortcuts that are used across all OS applications like Cmd+S, Cmd+O, Cmd+W. Is it possible with Chimera to use those? If not, it should be enabled. I'm aware that there are special 2-letter Chimera shortcuts (http://bit.ly/1Xr5uA4) but they are more confusing for beginners and therefore also disabled by default. We see a lot of user errors like saving the session with Cmd+S, then quitting Chimera with Cmd+Q (the only standard shortcut available, I believe) and then asking why their session info has not been saved. Included standard shortcuts as a feature in one of the next releases seems like a small thing with a lot of benefit. All the best, Jakob Jakob Suckale, PhD Lecturer in Biochemistry University of Tübingen +49-7071-29-73363
