It's usually called output current. Parameter Io on this TI part, page 4.

ADI calls it Maximum Output Current or Iout, page 3.

If you're still having trouble finding it post the datasheet or part number.

It's usually called Output Current. Parameter "Io" on this TI part, page 4.

ADI calls it Maximum Output Current or "Iout", page 3.

Occasionally, it is called Short Circuit Current or "Isc" like in this Linear part which is 5-9mA depending on operating conditions, pages 4 and 6. It is a slightly roundabout way of saying even if you short the output with 0 ohms, the op-amp can only supply 9mA so that is the max output current.
