Mageia forum

When Gnome 3.2 came out, I drew attention to the strange feature of the context menu in nautilus by right-clicking. Some letters are underlined in the menu first, in a split second underlining disappeares. This is clearly seen in the pictures that I made from my desktop.
In Gnome 3.0 I did not notice this behavior. Mageia 2 shipped with gnome 3.4, underlining in context menu still remains. Does anyone know what it is and how to disable it?

The underlining indicates a keyboard shortcut - pressing the key for an underlined letter selects that menu item. On my machine the underlining only goes away when I move the mouse - this may well be intended behaviour (if you are using the mouse, you are unlikely to be wanting the keyboard shortcuts).

I don't know any way of turning this feature off

I think GNOME did this long ago, IIRC it can be manually displayed again by holding down Alt key as this is what is usually used in combination to launch such menu shortcuts.

Thank you, guys, now I got the logics. But to me this behavior is more like a bug, so I'm pretty annoyed. I would be very grateful for the advice to disable the underlining completely (or make it constant).

Well, complain about this upstream at GNOME's bugzilla, but i'm afraid you won't be able to change something about that.
It's a well-known policy/problem that GNOME tries to make the desktop more simple by trying to get rid of additional options or try to hide them from the user.
See the infamous discussion about the shutdown button, or the one about the action when closing the lid, when the configurability for that was removed from GNOME.
