using the Perl gramar, if I have the cursor on a package name, like
Time::Mo|ment, (| is the cursor) and I try to get help, it should try to
get help on Time::Moment but right now it only uses Moment.
I had this problem with TM1 also but I fixed it by including : in the
definition of the "word". I don't know if this is still the way to do it on
TM2 or if there is a better way.
