*** Warning - newbie alert - Thank you in advance for your patience ***

In my Active Vocabulary I have a word called 'launch' where I say that word.
In my Commands I have a Program also called launch.
When I'm on my Linux box and I press Trigger it brings up an application/program.

How do I tie my 'launch' word to my 'launch' Command/Program so that when I say the word it will, well launch, the command/program?

TIA,
Matt
