Zoom in Zoom out button?

[black1]

Hello all, is there a zoom in zoom out button I can put on my hotas or we can only use my trackir5 zoom or view degree buttons like 30% view, 70% view..etc,etc ????

It seems to me there is only the 30/70/90° mode.
I've mapped the 30° to my joystick hotas as a quick zoom

Hey, you two: What about the search function of this forum?

Look at this thread for an extensive discussion and lots of solutions: How is variable zoom done?
