Thanks Guys!
Yes, it's to hide bones
I think I will use what you say : bones selection + Ctrl-I + shortcut to hide selected bones.
I'll try "shy bones" too, but that needs I activate "shy bones" before, and determinate at the beginning which bone is "shy" or not.

Hi
When I select a bone in Moho, I would like to mask quickly all the other bones (no selected), but I don't find how to make that in the interface? There is only "Mask selected bones".. but I need the inverse . Someone could help me?

When I open files in Moho, the play button (or space bar) works only once, and doesn't work after. I must close Moho and reopen. And again and again... somebody knows what I can do ?

Great!!!! Thank you very much!!!

Somedy knows if it's possible to display QUICKLY all layers with keyframes on the timeline ? I know we can select layers one by one to display them on the timeline, but if we don't know which layer has keyframes, we must select one by one to see them, and it's very long. I hope it's possible
