Unresponsive right click. Which key to replace right click?

So I've played so much league to the point where my left click is almost broken. my mouse's right click is very unresponsive. It would take a several right clicks before my champion moved/attacked. It's very hard for me to kite and farm as an adc. Which key would be the best alternative for right click? I tried using shift left click but holding shift prevents you from using actives.
