Making custom actions

OVD

Hey there, 

For a while I've been trying to figure out how to make more of my own custom buttons for the toolbar. 

I know the process for taking something in the Content Library and making a custom action for it then going through F3 to make the button. 

But I haven't found/figured out yet how to do something a little more advanced. 

For example, in a custom figure I've made, it can be approximated as a tentacle or a worm in its rigging. Basically one big long chain of bones. 

I'd ideally like to create a shortcut or button that selects all the children from the selected bone and also selects all the bones in the Parameters tab as well. 

Is there a guide around on how to accomplish something like this? Is it even possible? 

Thanks

You would probably have to write a script.
