Thanks for the file, kelly.
When I saw your initial question, I went to the
Main Menu>Window> Customization> Customize Commands.
I typed w into the shortcut field to see if anything could have led to this. My idea was that you might have pressed a key before that.
Anyway, besides the Coordinates Toggle, Sculpt was mentioned here in conjunction with the Sculpt Selection tool. (but it is not often that people use sculpt, so I excluded that, as if you were there, and pressed the w it should have shown you some results.
The W here shows you the mesh. Go to a brush tool (e.g., Pinch) while the object is selected. Press the w key, and again, etc. (doesn’t work while in point of polygon mode, must be Model or Object mode)
I hope that works for you.
