What I would like to do is create a form that
upon clicking a button would pass the corresponding function key
to the field in order to have the application progress.

string s = "foo";
switch(s)
{
   case "bar":
     Console.WriteLine("It was bar!");
     break;

   case "foo":
     Console.WriteLine("It was foo!");
     break;

   case "baz":
     Console.WriteLine("It was baz!");
     break;
}

fPause.ActionPerformed += myActionPerformedHandlerFunction;

...

void myActionPerformedHandlerFunction(...)
{
   STAFResult stafResult = ...
