On a related note, I once knew a programmer who didn't know how to use vi so she wrote C++ programs in Microsoft Word and cut and pasted them into a terminal. I don't know how long she kept her job for.
At least that way she would have complete control over the syntax coloring;).

I'm glad that you like the command. It seems like the menu option Allan Odgaard added to tm_dialog, has spured a lot of code completion related work, so it is likely that we will come up with a better key-combination for code-completion than ^M and one that is common to all language bundles
