How to select all surfaces of a group?

I can’t find a shortcut to select all surfaces of a BSP group.

My solution is selecting one surface of each BSP in the group and then pressing CTRL+B. It works but not easy.

any other solutions?

Shift + B Selects all surfaces belonging to the same brush of the currently selected surface
Shift + H Toggle show/hide FPS (Frames Per Second)
Shift + J Selects all surfaces that are adjacent to the currently selected surface
Shift + L Toggle show/hide Stats
Shift + N Deselects all selected surfaces
Shift + T Selects all surfaces with the same material as the currently selected surface
Shift + W Selects all the wall surfaces that are adjacent to the currently selected surface
