        --**Pressing hot key will do the following:
            -** 'Auto' Cast Q on target with prediction (WITHOUT MINION COLLISION - Make sure minions are not in the way)
            -** 'Auto' Cast E when in eRange
            -** 'Auto' AA'ing when in qbRange
            -** 'Toggle' Cast W when in wRange and turn off when out of range(credits to jbman for fixing)
            -** 'Toggle' Cast Ult(R) when health is at 15%(you can change this to what you like)
            -** 'Hot-Key' Q Harass with prediction (default letter S for harass)
