@elextr Are you sure that’s necessary? The items [are created](https://github.com/vfaronov/geany/blob/73476315635faab9a30102956362dce19a39b...) using [`gtk_image_menu_item_new_with_mnemonic`](https://developer.gnome.org/gtk3/stable/GtkImageMenuItem.html#gtk-image-menu...), and the mnemonics work for me under both GTK+ 2.24 and 3.18.
