Select menu, see submenus "Selection Mode... append" (allows building up a selection instead of always replacing it, or intersecting, as with a specific chain), "Chain...[chain ID]", "Residue... amino acid category" and/or "Residue... [residue name]" but the menu approach is more tedious/longer than commands.
