Specifies an accelerator key that is used by an interactive application to move the input focus to a particular field element.Reference_Syntax.accessKey = “character“
The value of this attribute is a single character. When the user synchronously presses the platform-specific modifier key and the single character, the form’s focus shifts to this field. On Windows systems, the modifier key is the ALT key and on Mac OS systems, it is the OPTION key.For example, if the form author sets the accessKey of a field to f and a Windows user presses Alt+f, the focus shifts to that field.When designing forms that include accelerator keys, form designers should instruct the users about the availability of the accelerator keys.
