Search for previously defined messages in Mathematica

Question

Mathematica, by default, defines many useful messages for signaling common errors, such as functions called with the wrong number of arguments or files that were not found. In general, I prefer to use existing, specific messages, where possible, because it facilitates their processing using mechanisms such as Check, Quietand On/ Off. However, all my attempts to find which messages are currently identified have failed; obvious approaches like

DownValues[MessageName] 

don't work at all.

Is there a trick I'm missing?

Thanks in advance.
