When I use GNOME Shell, and GNOME Connectin Manager program, and trying Alt+S in MidnightCommander (all inside GNOME Connection Manager), I get window context menu opened, instead of "search action" shortcut in MC. Well, its not only about this program, but few more.
Can not use here trick with "Keyboard shortcuts" as described here. There is no such meniutem as "Keyboard shortcuts".
Also using trick with Escape key is not good, as it's workaraound, not a solution.
How to simply disable this particular Alt key behaviour. Help me preatty please!
