TL; DR; Alt + F1 , then 1
First check your key combination for the "Select to .." item in the navigation menu.

Click in the file you are editing, press the shortcut key for "Select To" .. then press 1.
I changed the hotkey for selection in Alt + 1 so that my keyboard shortcut was easy to remember Alt + 1 , 1
