Reads messages in a specified range. bb with an argument (eg, "bb 1-3") is a shortcut for "bb read", except that for historical reasons, "bb all" maps to "bb read = new" not "bb read = all" Syntax: bb read = 20 (read message 20) bb 20 (same) bb read = #foo : 20 (read message 20 on board #foo) bb #foo = 20 (same)
