Trying to create a shortcut for selecting a font

Dear List members,
i am trying to create a shortcut, in order to select a particular font
in xelatex.

I would like to define a short cut that insert this string.

{\Hiero }, as I am using a particular font for the transliteration of
Egyptian hieroglyphs different from the main font.

I would like to select as shortcut something like CTRL+ALT+h

If someone can help me and show how such thing can be achieved, I will
be extremely grateful.
