Ubuntu – Ubuntu: “Editable Menu Accelerators” (on a per app basis). Where is this option


I keep seeing references to a config option calld Editable Menu Accelerators or Editable Menu Shortcut Keys.
This is exactly what I need, but all the directions I've read about how to find that feature lead me to a dead-end.

I am running with Ubuntu 10.4, and have checked its help file Desktop User Guide.
In Section Interface Preferences it says:

"...the Interface tabbed section in the Appearance preference tool  
    to customize the appearance of menus, menubars, and toolbars  
    for applications that are part of GNOME."

This Interface tab does not exist in Ubuntu 10.4 (… okay, who moved it?! .. where is i?)
Is this feature still available?
I assume it does exist, and is now accessible some other way… but how?

PS: To clarify… I want to modify a menu-item accelerator for a specific app (not a system-wide hot-key)

It seems that GNOME decided to remove the interface tab because "basically everything there is a user experience design cop-out. It only belongs in a tweak UI tool." So now the only way to enable that option is hidden deep in the gconf settings.

Launch gconf-editor from the terminal or the "Run Application" dialog (Alt-F2).

Navigate to desktop>gnome>interface and check can_change_accels

Or just run this line in a terminal:

gconftool --set /desktop/gnome/interface/can_change_accels --type=bool True
