Using middle mouse click

[Contro]

I am thinking about the middle mouse click
One of my often moves is go to see the main goldmine window
Goldmine is my CRM and knowledge base. I use continually.
So the clicks to make active the goldmine windows are very very often. May be 300 times a day.
At the present I need to move the mouse to click on the icon in the task bar or in the window in the task bar (excuse my english) . I'll put a screenshot.
Inside FF  when i click in the middle mouse click I paste. But I really i am used to use Ditto (Ditto is a multi clipboard very special) or Ctrl-V.
MilesAhead script ReOpen give the possibility to use the middle mouse click to hotkey and see a list.
So.
I think for me is specially useful that the middle mouse click have the following special function.

Really two functions.

If goldmine is open :
Activate his window

If Goldmine is not open, then open the program with this command :

Y:\GoldminePrg\gmw5.exe /i:esm /u:JOSE /p:

The main process of Goldmine is : gmw5.exe

I have taken the Goldmine window information with ActiveWindow info

Solved with help of Miles Ahead

Code

; ~MButton::   ; como no veo interacción con el comando anterior lo pongo como comentario y pruebo con el siguiente : 
; ~MButton
MButton::
; Process,Exist,gmw5.exe
  Process, Exist, gmw5.exe
  if (ErrorLevel) ; process is running
;    WinActivate, gmw5_window_title ; whatever the title or class is
     WinActivate, GoldMine 5.5  ; creo que este es el título. sí lo es. Comprobado con AA
  else
;    Run, Y:\GoldminePrg\gmw5.exe /i:esm /u:JOSE /p:
     Run Y:\GoldminePrg\gmw5.exe /i:esm /u:JOSE /p:
  return
  
; lo único es que desactiva el botón central en FF para ir a pestaña nueva enlace

What I need now is very similar to the middle button script but more simple : Don't require a hotkey (or shorcut combination)

But is for Firefox

And Firefox uses tabs and have many many names for the active window

so I try a script with three most common possible situation, but the command if don't accept

This is the code :

Code

  Process, Exist, firefox.exe
  if (ErrorLevel) ; process is running
;    WinActivate, Administrador de complementos - Mozilla Firefox
    WinActivate, Webs Generales - Speed Dial - Mozilla Firefox
;    WinActivate, Búsqueda personalizada de Google - Mozilla Firefox
;    WinActivate,
  else
     Run M:\Archivos de programa\Mozilla Firefox\firefox.exe
  return

Only admits one winactivation Line. And I don't know what window need finally to be activated.

How can i use more than one window ?

Best Regards
