To your first question, this will come with experience, in this case you want to update the contect attribute TEXT with a new value, so you would use the method SET_ATTRIBUTE to do so. the WD_CONTEXT is the built in reference to the context object, so you can directly call its methods.

Also, to answer your second question, you can find out what WD_CONTEXT references by simply double clicking on it. It is a instance of an interface IF_WD_CONTEXT_NODE.
