I never remembered the "sw" keyword

a small step for programmer
a big step for usability, especially for the non-native english speaker
among us

"tag" is not *that* long to write, and much mor easier to remember than
"sw"

For people already using your extension, it would be better to have two keywords
but I don't know if it's possible to to it

Still, I really think it would help a lot newcomers if you update the keyword
