Autohotkey 延迟像素搜索

如何将睡眠添加到enterpixel搜索本身？我想在按下热键后延迟功能

f1::    
enterPixelSearch,x1,y1,1,100,200,100,0x000000,2,Fast RGB 
    if(ErrorLevel == 0)
    {
        sleep, 20
        send
    } 

f1::
Sleep 1000
enterPixelSearch,x1,y1,1,100,200,100,0x000000,2,Fast RGB if(ErrorLevel == 0) { sleep, 20 send }
return
