The standard hot key to add a new item to InfoQube when outside that application is Windows + N – {Win}+N. Unfortunately, it appears that that hotkey is used by the Microsoft OneNote application, and that it cannot be changed in that application.
There would appear to be two ways to change the hot key in InfoQube:
If I attempt to use the first option, any attempt to edit the existing string and to enter {Win} causes random and uncontrollable changes to the suggested hotkey. The only sensible choice open to me is to press the escape key, and to revert to the existing setting. It may be significant that I am using a French AZERTY keyboard.
The second option is ineffective, because the hotkey I am trying to change is a system-wide choice which therefore does not appear in a standard InfoQube menu.
So, at this point in time, I have not succeeded in changing the standard hotkey and I am not able to add new items to InfoQube without first switching to that application.
