Extrude same amount multiple times quickly?

Hello everyone!
Is it possible to extrude something (vertex, edge, face) multiple times using the same amount?
Of course, I can type in the amount multiple times or duplicate the edge or face(s) that have been extruded.
But is there a quicker alternative that repeats the last extrude-process?

Many thanks in advance,

Extrude first time exact amount then Shift+R (Redo).

Thank you very much! That’s very useful!
