Customization of keyboard shortcuts

This is a proposal for a new SC to address the interference of keyboard shortcuts with Speech operation.

NEW SC Possibility:

Customized shortcut keys: Each customizable keyboard shortcut on the web page allows for a string of up to 20 characters to be assigned to the shortcut.

Understanding

Speech users can inadvertently activate custom controls by simply dictating a phrase on the page that contains a letter that has been assigned to a custom control. This requirement allows them to assign a phrase to the shortcut and reduces the possibility of accidental activation significantly.
