The invention claimed is: 1. A sink spray head with supply jet variation and flow rate regulation capabilities, the sink spray head comprising a body defining at least two distinct water supply areas in communication with a distribution chamber, flow of water from the distribution chamber to the water supply areas being controlled by a diverting first cut-off manipulable by distinct first and second selection keys accessible from outside the body, a regulation second cut-off being also provided for the regulation of the water flow rate, the first and second selection keys being operatively engageable with the second cut-off, the first and second selection keys each being equipped with a respective stem suitable for interacting with a first slide connected to the diverting first cut-off, the spray head including a second slide flanked with respect to the first slide and operatively engageable with the regulation second cut-off, the stem of the respective first and second selection keys being suitable for interacting with the second slide equipped with two inclined ramps substantially parallel to each other, both ramps suitable for being engaged by the stem of one of the first and second selection keys. 2. A sink spray head according to claim 1, wherein the spray head comprises a water delivery duct connected to the distribution chamber and defining a passage port controlled by the regulation second cut-off. 3. A sink spray head according to claim 1, wherein the distribution chamber defines a lower port controlling the communication with a central area and an upper port controlling the communication with a peripheral area of an indiscriminate jet. 4. A sink spray head according to claim 1, wherein the first slide defines a first and a second weathering opposite to each other and suitable for engaging respectively with the first selection key and the second selection key for transforming a translation of the respective first and second selection keys into a translation of a shaft of the first cut-off along a direction at least substantially perpendicular to the translation direction of the first and second selection keys. 5. A sink spray head according to claim 4, wherein the respective stems of the first and second selection keys end with a double weathering end. 6. A sink spray head according to claim 1, wherein the first and second selection keys are configured to execute an extra-stroke with respect to a stroke necessary to execute the variation of the supply jet, the extra-stroke defining the flow rate regulation through the engagement with the second slide. 7. A sink spray head according to claim 3, wherein the spray head comprises a first elastic device acting between an abutment spigot defined by the body and the first slide for bringing the diverting first cut-off back into abutment onto said upper port when a water flow determined by a tap placed upstream of the spray head is interrupted. 8. A sink spray head according to claim 7, wherein the spray head comprises a second elastic device acting between said second slide and an upper spigot defined by the body for bringing said regulation second cut-off back to an opening position at the end of the activation on the selection keys. 9. A sink spray head according to claim 6, wherein the stems of said first and second selection keys when the extra-stroke is executed engage with a side portion of said first slide for keeping it in the position taken. 10. A sink spray head according to claim 1, wherein the spray head comprises a ball joint interposed between the body and a mouth of connection to a water supply for modifying the conformation of the external shell of the spray head. 11. A spray head comprising: a fluid distribution chamber; a body defining at least two distinct water supply regions in fluid communication with the distribution chamber; a diverting first cut-off configured to control water flow from the fluid distribution chamber; a regulation second cut-off configured to regulate water flow to at least a portion of the spray head; a first slide coupled to the diverting first cut-off; a second slide coupled to the regulation second cut-off and including a first inclined ramp and a second inclined ramp, substantially parallel to the first inclined ramp; and first and second selection keys accessible from outside the body, each of the first and second selection keys including a stem, at least one of the stems being configured to interact with the first slide to move the diverting first cut-off and control fluid communication from the distribution chamber, at least one of the stems being configured to interact with at least one of the first and second ramps of the second slide to move the regulation second cut-off. 12. A spray head according to claim 11, further comprising: a water delivery duct in fluid communication with the distribution chamber and including a passage port, the regulation second cut-off being configured to control flow of water through the passage port. 13. A spray head according to claim 11, wherein the at least two distinct water supply regions include a peripheral region and a central region, the distribution chamber including a first port in fluid communication with the central region, and a second port in fluid communication with the peripheral region. 14. A spray head according to claim 11, wherein the first slide defines a first weathering and a second weathering, opposed to the first weathering, the first and second weatherings being configured to engage the first and second selection keys, respectively, to transform a translation of the corresponding one of the first and second selection keys into a translation of the diverting first cut-off. 15. A spray head according to claim 14, wherein the respective stems of the first and second selection keys terminate with a double weathering end. 16. A spray head according to claim 11, wherein the at least one of the first and second selection keys is configured to engage the first slide to move the diverting first cut-off and control fluid communication from the distribution chamber upon a first activation stroke to control variation of a jet supplied from the spray head, and to engage at least one of the first and second ramps of the second slide to move the regulation second cut-off upon a second activation stroke to regulate a water flow rate supplied to the spray head. 17. A spray head according to claim 13, further comprising: an abutment spigot formed by the body; and a first biasing device positioned between the abutment spigot and the first slide and configured to bias the diverting first cut-off into abutment with the second port when water flow upstream of the second port is interrupted. 18. A spray head according to claim 12, further comprising: an upper spigot formed by the body; and a second biasing device positioned between the second slide and the upper spigot, the regulation second cut-off being moveable between a first closed position in which the regulation second cut-off closes the passage port and a second open position in which the regulation second cut-off opens the passage port, activation of at least one of the first and second selection keys moving the regulation second cut-off toward the first closed position, the second biasing device being configured to bias the regulation second cut-off toward the first open position upon deactivation of the first and second selection keys. 19. A spray head according to claim 16, wherein at least one of the respective stems of the first and second selection keys engages a side portion of the first slide to maintain the first slide in a desired position upon the second activation stroke. 20. A spray head according to claim 11, further comprising: a ball joint positioned between the body and an external water supply device, the ball joint being configured to allow varying the positioning of the body with respect to the external water supply device. 21. A spray head according to claim 11, wherein the second cut-off is configured to be moved independently from one of the first and second selection keys.
