[Newbies] How to switch between Browsers

[Milan Zimmermann]

Hi,

I know this was answered before but I cannot find it. I have several browsers 
installed, the "default" (I guess that's the right name), OB, 
RefactoringBrowser, and maybe more that i do not know about.

So far I have sheepishly accepted the default depending on the image. How can 
i switch between them?

Thanks Milan
