CTRL + F8 (Zoom Function) in RTC Pages
In the ‘classic client’ for Microsoft Dynamics NAV (Formally Navision), the CTRL+F8 key was the zoom feature and allowed you to view the value in every single field on a form.
In the new Role Tailored Client (RTC), used in NAV 2009 and NAV 2013 this hotkey no longer works. However, the same functionality can be found with the About This Page feature in the RTC. Look at the image below for how you would access this (which you could now use Ctrl+Alt+f1). I guess they now thing you are more ambidextrous.
