Script editor hotkeys, navigation, etc

Is there a place in the manual or elsewhere describing editor navigation hotkeys, etc.? Also, what is the hotkey to dropdown scripting or expression functions for selection, or, should this be automatic as the function name is typed in?

Ctrl+Space would be used for the drop down for scripting. Attached below are the rest of the hotkeys that are available in designer.
