How to extrude faces in a row?

This is probably really easy, but I’m a noob and zmodelling is so confusing.

I’m trying to extrude the green faces as a single face- in maya, I’d just select those green faces and extrude.

How would I do this in zbrush? I can only extrude one face at a time, which I ‘ve already done in this screenshot

Zmodeller. Hold ALT and drag over the faces to make them a temporary (white) polygroup. Then QMesh (Single Polygroup, or Polygroup All or Polygroup Island). However QMesh will attach the leftmost extrusion to the block already protruding out. If you don’t want that then use Extrude rather than QMesh.

Thank you so much
