FVWM: A question on Actions in FvwmButtons

Hi all,

I am using FVWM2 with a button that launches Firefox, but the window
opens somewhere on the screen and I usually have to move it to a
"better" place.

My question is this: is it possible to add more than one action to the
button? Currently I have

  Action (Mouse 1) 'Exec exec firefox'

and I would like to have something like

  Action (Mouse 1) 'Exec exec firefox ; ResizeMove 90 90 5 5'

but I do not know how to add more than one action to the button.

Does anyone have a hint on that?

best regards,
