EDIT: I realize now that these shortcuts actually work in EDIT mode, but I want to know about POSE mode.
I'm trying to find shortcuts to make selecting bones in pose mode faster. Sometimes I want to select a few bones in a bone chain (like all the bones in the spine of the character, or all the bones in a finger), and I have to select each bone individually, which is fine but I wonder if there are shortcuts to make these things faster.
I know you can CTRL+L to select all linked bones, which is something. But a lot of times you don't want ALL the linked bones, just the ones down the chain (or up the chain), or a few bones in the middle of the chain... So I wonder if there is a way so select all linked bones between two bones, like you can select the shortest path between edges in edit mode by ctrl+clicking. Or maybe something like pressing the "+" sign would select one more bone down the chain.
Are there any shortcuts like that to make it easier and faster to select bones in pose mode?
