Sendkey on a particular foreground application, while Excel Sendkey Macro running in the background

There is an application on which i want to sendkey Tab , U ,Tab and then H by only pressing Ctrl+H.
(Ctrl + H) = sendkey(Tab , U , Tab and H.)
Can i make any macro in excel which will be running in the background and can send desired key stroke on a particular application running in foreground , when i press any assiaghned button.
