Hypertext commands

FM 2017 allows the insertion of 26 different hypertext commands: Insert > Hypertext.

Some questions belonging to two commands:

Message Client

The text field of the Hypertext pod shows: message

Why not "message openfile filename" as in previous FM versions?

Multimedia Object Link

The text field of the Hypertext pod shows: command value

Why not "multimedia objectId type command value" as in previous FM versions?
