 Using the keyword *checkqeq* with the value *no* turns off the check
 for the QEq fixes, allowing a simulation to be run without charge
 equilibration. In this case, the static charges you assign to each
 atom will be used for computing the electrostatic interactions in
-the system. See the :doc:`fix qeq/reaxff <fix_qeq_reaxff>` or
