+Only the {lj/class2} pair style support the use of the
+{inner}, {middle}, and {outer} keywords of the "run_style
+respa"_run_style.html command, meaning the pairwise forces can be
+partitioned by distance at different levels of the rRESPA hierarchy.
+The other styles only support the {pair} keyword of run_style respa.
+See the "run_style"_run_style.html command for details.
