How to merge or join bones?

I´ve tried

j
ctrl-j
alt-m
w

But, nothing works, I´m in Edit mode, windows, blender 2.37

Thanks!

ALE

You can’t, delete one of them with X in Edit mode and drag the tip or heel of the other one to the position of the deleted one. Best to delete the one that’s connected to the one you’ll keep; ie, lowest in the heirarchy.
