Documentation
Non-nil means use a separate selection buffer for each label type.
These buffers are kept from one selection to the next and need not to be
created for each use - so the menu generally comes up faster. The
selection buffers will be erased (and therefore updated) automatically
when new labels in its category are added. See the variable
reftex-auto-update-selection-buffers.
Probably introduced at or before Emacs version 20.3.
