I just wrote one that should work. The only thing is you need to write in your chrome's install directory in the Run method right now.
AutoIt script is as follows:
Func chromeTabs($num)
Run() ;Insert Chrome's install directory here
While $num > 0
Send("^t")
$num -= 1
$time = TimerInit()
While TimerDiff($time) < 1000
$time = $time
WEnd
If $num < 249 Then Send("^w")
WEnd
EndFunc
chromeTabs(250)
Func chromeTabs($num) Run() ;Insert Chrome's install directory here While $num > 0 Send("^t") $num -= 1 $time = TimerInit() While TimerDiff($time) < 1000 $time = $time WEnd If $num < 249 Then Send("^w") WEnd EndFunc chromeTabs(250)
