How to activate Hotkeys to working fast with Maya 2014 MTK

Something that is extremely useful when modeling using MTK are the Transform Constraints (TC), and more useful is to have them at hand in our hotkeys instead of clicking with the mouse

In my case I have assigned the "T," "Y" "U" keys on the keyboard to, respectively, Edge Slide, Slide Surface and Off to disable the TC

I also put in picture how to activate the MTK tool itself (I have it as hotkey in "A")
