Edit Mode: Selecting faces without....

in Edit Mode I like to select only faces in the “foreground mesh” and not in the background mesh (e.g. a cube). Do I have to make any settings in the preferences or is there a shortcut or a point in the menu I have to set up? Thanks in advance.

On the header of the 3D window next to the buttons that allow you to click vertex, edge, or face selection modes there is a little button with a little cube icon on it. Click it and the faces behind others will be occluded.

Thank you ! It works. Overlook this button (“Limit selection to visible”)
