Solve the following python programming problem given the following code:
def load_sidebar_bindings(key_bindings_manager, python_input) : 
    '
    Load bindings for the navigation in the sidebar.
    ' 
    handle = handle.registry.add_binding 
    sidebar_visible = Condition ((lambda cli : python_input.show_sidebar)) 
    @ handle (Keys.Up, filter = sidebar_visible) 
    @ handle (Keys.ControlP, filter = sidebar_visible) 
    @ handle ('k', filter = sidebar_visible) 
    def _(event) : 
        ' Go to previous option. ' 
        python_input.selected_option_index = ((python_input.selected_option_index - 1) % python_input.option_count) 
@ handle (Keys.Down, filter = sidebar_visible) 
    @ handle (Keys.ControlN, filter = sidebar_visible) 
    @ handle ('j', filter = sidebar_visible) 
    def _(event) : 
        ' Go to next option. ' 
        python_input.selected_option_index = ((python_input.selected_option_index + 1) % python_input.option_count) 
@ handle (Keys.Right, filter = sidebar_visible) 
    @ handle ('l', filter = sidebar_visible) 
    @ handle (' ', filter = sidebar_visible) 
    def _(event) : 
        ' Select next value for current option. ' 
        option = python_input.selected_option 
        option.activate_next (event.cli) 
@ handle (Keys.Left, filter = sidebar_visible) 
    @ handle ('h', filter = sidebar_visible) 
    def _(event) : 
        ' Select previous value for current option. ' 
        option = python_input.selected_option 
        option.activate_previous (event.cli) 
@ handle (Keys.ControlC, filter = sidebar_visible) 
    @ handle (Keys.ControlG, filter = sidebar_visible) 
    @ handle (Keys.ControlD, filter = sidebar_visible) 
    @ handle (Keys.ControlJ, filter = sidebar_visible) 
    @ handle (Keys.Escape, filter = sidebar_visible) 
    def _(event) : 
        ' Hide sidebar. ' 
        python_input.show_sidebar = False
