Capitalising Sounds

[insert_cliche_here]

I did a search but only found one thread that didn't really answer my question, so I'm gonna go ahead and ask.
Should sounds be capitalised in a screenplay? Some people seem to say they shouldn't and others say they should.
What's the purpose of capitalising?
And if you do hit caps lock, for what sounds should you do it?

I hope that makes sense

In your shot list / personal shooting script. Also you can do storyboards etc.

What we're getting into is the difference between a script I write for myself to direct, and one written for somebody else (as was noted above). If at the moment I am writing it (a script for my own use) I have something I want to make sure and remember (like a shot, a transition, a costume, etc...) I may put it in the script. but if I am writing a script to try and sell, or for someone else to produce, it's pretty much dialogue and action only. Those thigs (costumes, detailed blocking, what emotions the character expresses, etc...) Are for the director to decide, not me as the screenwriter. As was said, that stuff goes in the shooting script, shot list, etc...

Yeah, I'm talking about spec scripts, which I write exclusively.

My director does his own shooting script afterwards, which includes the shots/direction notes etc.
