error in documentation

Howdy,
I think there are an error in the Lyx tutorial (in Lyx menu: help>tutorial)
in chapter 4 "Using Math"
it says: "(...) Happily, LyX has WYSIWYM support for equations. (...)"
and it says: "(...) math commands can be typed in normally, but they 
will show up in a WYSIWYM fashion (...)"
in the context it should say WYSIWYG instead of WYSIWYM.
it is a little detail but may confuse new users.
