FAQ:

How do I assign different keyboard shortcuts?

Answer:

If you want to rebind a shortcut, Galeon supports the standard GTK+ way of changing shortcuts: simply hover over the menu option with the mouse pointer and press the keyboard shortcut you want to rebind it to.

To delete a keyboard assignment, press the Backspace key while you are on the menu entry.

If the shortcut doesn't change, then you need to enable the feature in gtk. This can be achieved in 2 ways:

  1. If you are running GNOME then you can enable Editable menu accelerators in the Menu and Toolbars control centre dialogue, or alternatively run:

    gconftool-2 -s -t bool /desktop/gnome/interface/can_change_accels true
  2. If you don't run GNOME, put the following in your ~/.gtkrc-2.0 file:

    gtk-can-change-accels=1
