Shift-1 and Shift-2 are changing paragraph styles; not a Keyboard Shortcut
Hello -- working in a file from somebody I am not still in contact with. Shift-1 (!) and Shift-2 (@) work normally in new documents or other former files I've created, but in this document, Shift-1 and Shift-2 change the Paragraph Style back and forth from one paragraph style to another.
This does not seem to be a Keyboard Shortcut! I've gone through them with a fine tooth comb and can't find anything in Keyboard Shortcuts assigning Shift-1 and Shift-2 to this function. Any idea of how in this particular document the ! and @ shift-1 and shift-2 keystrokes have been dedicated to paragraph style switching?
