Hello verovero, for custom graphical controls using MQL5 language, please take a look at this article.

Not possible with mql5 only, you need to use Winapi for that (show input parameters window).
 

Thank you sir. 

I'm finish.

This's my code.

#include <WinUser32.mqh>

if(id==CHARTEVENT_OBJECT_CLICK){ 
     if(clickedChartObject=="ObjectName") keybd_event(118,0,0,0); // F7
}
