Objects stopped rotating and scaling for me

[chuck_starchaser]

I must have hit one of those keyboard shortcuts by accident… Now in Object mode objects no longer rotate for me. They circulate around the cursor, but without changing the facing.
And I can only scale in edit mode.
How do I get Blender back to sanity?
TIA

EDIT: version 2.76

(Note: Using 2.79; mileage may vary)
You may have “Manipulate center points” selected.
Try ALT-, (ALT-COMMA)

BINGO! Thanks, bro.
