Equivalent of Dragon NaturallySpeaking's HeardWord function in Dragon Dictate 4 In Dragon NaturallySpeaking's Advanced Scripting Command on Windows, HeardWord is a function that enables Dragon NaturallySpeaking to behave as if the specified word, word sequence, or voice command was received by the recognizer. HeardWord can be used to create a command that executes a series of other commands, or that has the same function as an existing command but a different name.

Here is an example to type a closing remark, in bold type, at the end of a document.

HeardWord "go", "to", "bottom"
HeardWord "set", "font", "bold"
Wait 1
SendDragonKeys "{Enter 2}" + "This document was dictated using Dragon NaturallySpeaking."


In Dragon Dictate 4, is there any way to write a voice command that calls other voice commands (e.g. a voice command that would call the built-in command "Cap")? 

Since I bought the product more than six month ago I do not have access to the customer support anymore. Searching on Google didn't bring any interesting results.
It can depends in which application you dictate. 

The online help is accessible by clicking on the Dragon icon in the menu bar. 

Or click here: http://www.nuance.com/products/help/dragon/dragon-for-mac/enx/Content/GetStarted.htm

Else, there is the Commands manager in the same menu in the menu bar.

On Mac, you can use Applescript with Dragon Command manager.
