Pose as Rest Pose

Conversely, you may define the current pose as the new rest pose (i.e. « apply » current transformations to the Edit Mode), When you do so, the skinned objects/geometry is also reset to its default, undeformed state, which generally means you will have to skin it again.

Pose Selected as Rest Pose

Same as Pose as Rest Pose but only applies to selected bones.
