I Edit: Actually, there's a version 3 of the keyguide that thealx updated linked from the wiki main page. I don't think I've noticed that before. Thealx, if you see this, could you let me know how you edited the file?
I think it was Foxit PhantomPDF (ver. 6.1 in my case), it has tool "Edit object" to apply changes to the existing texts or copy/past any text or image.
If you will apply changes, please also add Ctrl+V for cockpit light
