If this is present the default shortcut_limit of 100 is changed to <integer>.
The shortcut_limit value defines the highest shortcut_name_<n> and shortcut_title_<n> for which CDDataExtract will look e.g.
shortcut_limit=3
will mean that CDDataExtract will try to find shortcut_name_1, shortcut_title_1, shortcut_name_2, shortcut_title_2, shortcut_name_3 and shortcut_title_3 (but none of them has to exist).
