When I go into Activity settings and open the dialog box for a specific activity there's an option to set a "Shortcut for switching to this activity". I've tried to set various key combinations as the shortcut but it doesn't seem to save.

This image shows the setting that I'm talking about.


I set the shortcut to Alt+b, and click ok.


I notice that when I click OK the Help button in the bottom left is highlighted blue. That seems strange but clicking it doesn't take me anywhere.


Then when I open the settings for that activity again, no shortcut is set.


No matter what key combination I use it doesn't save the shortcut. Am I doing this wrong or is this a bug?
