hiding editor doesn't set focus to output panel
I'm a keyboard kinda guy. I hate the transition to mouse from keyboard. In that spirit...
After executing a query if you hide the editor by hitting command+9, you cannot subsequently expand the query panel results using command+alt+shift+0. However if you then click on the first element of the query results and repeat the keyboard shortcut, the objects and expanded.
Perhaps the solution is to set the focus on the first item in the query results if one hides the editor (and vice versa -- hiding the query results sets the focus in the editor).
