"Pose Brush" in the manual? / URL?

I was searching for “Pose Brush” in the manual and had issues: without the Google-esque ability to use quotation marks to constrain searches, the search results were not useful.

https://docs.blender.org/manual/en/2.81/sculpt_paint/weight_paint/tool_settings/brush.html?highlight=pose%20brush

So I resorted to eyeballing the TOC, but it didn’t jump out at me under the Sculpting category, my guess as to which section it would be in. Is it in a different category?

Am I using the wrong search terms? All the marketing references seem to use “Pose Brush”.

+: using the context sensitive RMB manual link did not take me to the tool either.
(I realize that there may be many non-Blender.org resources that cover it, but I do like things to be addressed in the official manuals.)

I think it just wasn’t documented in 2.81 manual for some reason. It seems there for current (2.82) manual though:

Ahh. Thanks.

—Although, this part is pretty opaque:
“Pose Origin Offset
Offset of the pose origin in relation to the brush radius. This is useful to manipulate areas with a lot of complex shapes like fingers.”
