Go to Edit>Keyboard shotcuts. In the search bar at the top, enter "-layers-" to restrict the list to possible candidates. Then select the one you want (one of the "python-fu-" ones), click on the line, and then enter the key combo you would like to use as a short-cut (caution: many are already used, so you get told about that, but you don't really know which important shortcut you'll override...).
