Huh. I didn't do anything like that.

I found InputAutoReplacements in Options (with Global selected), and 
manually added an entry to the List. That is, I positioned the cursor at 
the end of the list but inside the brackets and typed (exactly):

"cg"->"Clear[\"Global`*\"]"

Then I clicked Apply, and that was it.

It's exactly what we'd naturally think the rule would be except for two 
things. (1) Both arguments of the rule are strings, and (2) to get quotes 
inside the target string, you need \", not just ".
