k_send - Same as "send", except that it takes a "set" message to change target. k_receiver - Same as "receive", except that it takes a "set" message to change source. k_send~ - Same as "send~", except that it takes a "set" message to change target. k_strcat - appends a symbol to a text and sends out a new symbol.

(These four objects, in addition to the receive~ object, may perhaps make pd programming a bit more modular).
