    shell: Add missed shortcut keys in help overlay
    
    A few shortcut keys were missed and it could make
    users get confused that one of them exist or not.
    
    Add following keys
    - Ctrl+D for adding bookmark.
    - Ctrl+I for inverting colors.
    - D for toggling dual page.
    - N for going to next page.
    - P for going to previous page.
    - F9 for toggling sidebar.
    - F7 for toggling caret navigation.
    
    Closes #890, #786
