Is there a way to copy similer weights to other bones?

I was wondering if there is a tool or easy way in blender to copy the weight of a set of bones and paste them onto another one and if the mesh is modeled the same in that area then the weight will effect it the same too.

In other words I’m trying to weight fingers right now and I just thought since they’re all pretty much the same shape it would be SOOO much easier if I could just copy and paste the wieght of one finger to the rest!:eyebrowlift:
