What's the difference between coupler and keyboard?
Coupler
Definition:
(n.) One who couples; that which couples, as a link, ring, or shackle, to connect cars.
Example Sentences:

(18) We measured TRAcP-activity fluorometrically after extraction of the product naphthol-AS-BI, using the same staining solution as in cytochemical method, but without the coupler.
(19) Five frequency responses were used, two of them were defined by their response in a 2-cm3 coupler: 1) uniform coupler gain (UCG), and 2) 6 dB per rise (6 dB).
(20) The effect of hyperosmolarity was shown only in cells stimulated by lipolytic hormones, and the effects were still evident in the presence of high concentrations of theophylline, indicating the effect of hyperosmolarity is to facilitate hormone action on the receptor-coupler system of the adipocyte membrane.
Keyboard
Definition:
(n.) The whole arrangement, or one range, of the keys of an organ, typewriter, etc.
Example Sentences:
