There was a TECO compresser TECO macro, but that is a more limited beast: it simply would compress out any spaces between commands, and convert string delimiters to their short form. This definitely did make them smaller and slightly faster, as well as harder to read.
There was also, on TOPS-10, a TECO that would read the command string and compile it into machine code, then execute the result. I think it came from Stevens University, but that may just be a confused memory.
