I'm assuming that the OP is working on some project, since he said
that he wanted to find some function or variable in one of the
buffers.  Presumably, those buffers all visit files that belong to
some project, and if so, they all live in a single directory, or in a
single tree under the same parent directory.  Thus `A' is appropriate.
