The main menu for Casual Info is casual-info-tmenu. Bind this menu in the keymap Info-mode-map as follows in your initialization file.
(keymap-set Info-mode-map "C-o" #'casual-info-tmenu)
While not required, adding this configuration to your Emacs initialization file will synchronize keybindings between Casual Info and the Info reader. A nice visual improvement is to use hl-line-mode to highlight the line where the cursor is at. Enabling scroll-lock-mode will enable scrolling the buffer for content that is larger than its window size with the navigation keys.
