OS 10.5 - Right Click on Alias?

Hi there,

I'm a mac newb, so my apologies if this is a dumb question.

I've added a folder to my dock, to the right of the "road", in order to use it as a stack.

I have it in list view.

Occasionally, I want to open I file from that stack, with a different program than it's default is set to. So, I try to right-click on the file to choose the "open with" prompt, only to find that it opens the file.

Is there a way to get right-click menu options on aliases of files that live in your dock stack?

Thanks!
