I just had Word go crazy

all of a sudden I start trying to type quotation marks and question marks and instead I keep getting braces and dashes. Okay, this is weird. What hotkey did I accidentally press to get in this mode? It was only when I started accidentally getting “enyays” (tilde-ns) that it hit me itd probably switched me to a spanish-key-layout without my knowing. Poking around in windows language settings I finally found the culprit. Apparently leftalt-shift is a hotkey to switch key layouts. So even though it was saying “english key layout selected” visually in the settings…it wasn’t…but a quick repeating of the hotkey restored nomalacy.
