There is no space between the type and the variable name in the qtest.html documentation.

For example function "void QTest keyClick( QWidget *widget , charkey , Qt::KeyboardModifiers modifier=Qt::NoModifier , int delay=-1 ) [static]", there should be "char key" not "charkey" as a parameter. There are also few other functions with the same "typo" and one with "charascii".
