Kite

HI! I'm playing for 7 months and recently i discover what kiting is and how much it s important for an ADC. I know you can do it with Shift+right click or A+left click. What is better? How can i subtiute SHIFT+right click with T+ right click(that is substitute Shift with T) because i play with my pinky on q and my index on R, so shift is near impossible to use and i can easily press R with my index
