We GNOME translators can preview many of the new features because, well, we translate them. But today translating Orca proved even more useful: I discovered that Alt+F6 switches the focus do daughter windows. Now, that’s how you can focus a dialog after switching to another application and back to the application with the open dialog. (By the way, this keybinding is editable in the System?Preferences menu.) I just feel like when I read from Ross Burton how useful is middle-clicking a scroll bar.
Thank you, Orca developers. Besides writing well recognized software and excellent translator comments, you proved to be very instructive 
Thanks for the middle-click tip, I didn’t know it!
I wonder why jumping to the position is not the default behaviour (normal click) though…
