Now I'm not sure if I understand exactly what he's doing here, but it looks like something along those lines: rather than inputting what he wants directly via the keyboard, he has to choose a pattern (like variable-operator-variable) from a drop-down list, and then tab between the fields to fill in the pattern. A poor analogy might be the difference between speaking words verbally to form a sentence vs. shuffling through a stack of index cards to find the right words to arrange on a table to form a sentence. The latter would be useful if you were just learning a language, but once you know how to speak it, that would be an enormous waste of time.
