How to attach different bones which are not linked

I want to know how can I attach or connect or link multiple bones, which will be created by new bone command.

Now I want to use these bones as child bones,now don’t tell me to use child bone feature.

I’m asking solution because couldn’t find shortcut key for child bone, that’s it.

If you know both solution plz tell them.

What do you mean by “not linked”? Is it on a different layer? If it’s still within the same layer, you can assign its parent to the desired bone. Alternatively, you can export the origin of the parent, then for the child bone’s origin, apply an ‘add’ converter and link the rhs or lhs to the previously exported bone origin.

The only way that I know know of for “linking” familys of bones([parent+childre] to [parent+children]) is moving them though a group.

I did that in my latest Rig project.
Warning: Disable the loop layer; kind of heavy to preview.
Hope this was informative.
