Right Click applies Watershed

[pedrogalher]

Hi,

I have been using this tool for more than a year and I have always used the right-click in the mouse to apply the watershed.
Today, I was looking through the shortcut list, and saw that to apply watershed one must press the space bar.

So, my question is: is the option of applying the watershed with the right-click a feature or a bug (that I have been taken advantage of)?

Thank you!
Pedro
