Just watch some AutoIT tutorials, this is very simple.
Almost everything you need is :
• MouseClick ( "button" [, x, y [, clicks = 1 [, speed = 10]]] )
• MouseMove ( x, y [, speed = 10] )
• Send ( "keys" [, flag = 0] ) << if you want to click f5, it must be {F5} instead of "keys" ant if you want to click enter, it must be {ENTER}
• Ant just to skip some time you can use sleep function - Sleep(1000) << 1000 = 1 second
I hope it will help for you, good luck
