Expanding an item can be accomplished in several ways. Keep in mind that `expanding' means that you are creating a view by combining the current item (as the root of the view) with a GPD used when expanding an item of that type (see chapter 8 for a full description of expansion). Given that you understand that, you have two choices for the kind of expansion. You can either expand the item in a new window or reuse the same window. To expand in a new window, you can either type meta-l meta-e with the cursor in the item you want to expand or you can click on the item using the left mouse button while pushing the ctrl- button.
To expand and reuse the same window, either type meta-l meta-E (note that it's a capital E) with the cursor in the item you want to expand or you can click on the item using the middle mouse button while pushing the ctrl- button.
Both of these assume that you haven't changed the translations for these particular sequences.
Under certain circumstances (when the GPD is so defined, e.g. the
`folder' GPD), when you expand a newly-created item for the first time,
the system will pop up a window to ask you which view to use in
expanding. This means that you should fill in the `empty: item' with
the name of the GPD that you wish to use in the expansion. This will
then be saved and used from that point on unless you change the name of
the GPD (see section 3.1) See section 5.5 for
further information.
