what is ttt
 

sometimes in a response, some posters write "ttt". What does this mean

It means "To the top." Someone has brought a post to top for any number of reasons, including:
*The original poster is hoping for most responses.
*A helpful person is bringing an older thread to the top for another person who is seeking information that topped post might provide.

Try The Text (search)

It does not mean "Try The Text". It means "To The Top". That's what it means here.

thanks for the explanation!
