An essential shot that never seems to get mentioned

Late forehands. An essential shot in singles but never seems to be spoken about. Without this shot covering court can become very difficult.
The general pattern seems to be
Lunge with racket foot into rear court.
Prepare by supinating forearm.
Then play a shot:
A straight clear
A straight drop or drive
or a cross court shot which is hit with slice seems easiest.

Is this shot taught and drilled much?

Any hints or tips?
