link expansion options

11.7: adde/outliner/links whose default is
[target replaces current link instead of current page]:
. outlines are like a tree of links except that
instead of the destination replacing the current view
it becomes added to it .
. notice that this is a generalizable link option:
a link would have a default activity,
but by using the context menu, you could select either
{ target replaces current link instead of current page
, target replaces current page
, target lauches in new {window, tab, todo list}
}.
