Right click custom menu over a sprite

All right I’m looking for some advice here, hopefully good advice.

Basically I have lot of text fields that are rendered dynamically, and I want the user to be able to right click on one and edit it.

Is it good practise to use the right-click bring up custom menu on a sprite. And is the method guaranteed to work accross all browsers? Do mac mice have right mouse click buttons?:sen:

And if not, what would be a good work around. Maybe bringing up a yahoo astra message box with the two options one for left mouse click, one for right click and edit text field?

Help!
