i would like to use

void OnChartEvent(const int id,         // Event ID
                  const long& lparam,   // Parameter of type long event
                  const double& dparam, // Parameter of type double event
                  const string& sparam  // Parameter of type string events
                  )
   {

   if (id == CHARTEVENT_KEYDOWN)
   if (lparam == 114) // F3 has been pressed
      {
      Alert ("you are gonna mess around With thing that might stop the EA working properly");
      }
   }

unfortunately it doesn't work maybe MetaQuotes will fix it some time

I thought we can just put any keydown masking and it would work OOTB. Guess not, huh?

no there is a few keys that doesn't work one of them is "F3"

[Ian Venner]

Perhaps F3 is reserved for future terminal use ...

I believe that it doesn't work with any of the F keys

so that is probably why you cant use it in mql4. Most times you wouldnt want to trigger a terminal function every time you use the f key for an EA function.

Like when you click F8 ... F9 ... F12 ... and so on.

Alert ("you are about to mess around With thing that might stop the EA working properly");
