It's happening that numeric keypads stop working as nudge shortcut.
They work if I push them while holding alt gr key.
It is possible to activate the normal behaviour pressing 0 while holding windows logo.
It's happening under windows 10. Does anybody know any explanation about?

maybe you need to turn on numlock?

Zero on the numeric keypad activates Enhanced Editing mode where numeric keys become navigation and editing buttons, replacing the nudge function. This mode will display a vertical gray/white bar in the active track; that's the Enhanced Editing cursor. If you're seeing that cursor, another press on the 0 key with no modifiers should return the keypad to normal mode.

Thank you Brundlefly, very, very much!

Sure thing. Glad to help.
