You should be able to use method_missing, but you could also do 
something like

   class Handler

     [ 100, 250, 500 ].each do |factor|
       define_method("menu_zoom_#{factor}_activate") do
         @display.zoom(factor)
       end
     end

   end

or for some more syntax sugar define a class method

   class Handler

     class << self
       def zoom_methods(*factors)
         ...see above...
       end
     end

     zoom_methods 100, 250, 500

   end
