-In order to reference a series of keys to be pressed in succession, a dash (**-**) will separate the keys.  Furthermore,​ since some key combinations require holding a key while pressing another, this action is denoted by a superscript <​sup>​**hold**</​sup>​.+In order to reference a series of keys to be pressed in succession, a dash (**-**) will separate the keys.
