The string 14733 is technically incorrect and hard to understand for users. It should be revised.
The current string content is
When enabled, VRChat will attempt to match your current finger pose against the standard VRChat hand poses.
It is for Avatar Gestures (see attached image on Crowdin).
I tested it on Vive. When disabled, the app stops controlling avatar fingers with the pad. This behavior is the exact same as the explanation in the doc ( https://docs.vrchat.com/docs/gesture-toggle#avatars-30 ), though the terms ("Avatar Gestures" and "Gesture Toggle") differ.
And I tested on Quest2 with its hand tracking ( https://docs.vrchat.com/docs/vrchat-202241#quest-hand-tracking ). This option seems to change nothing.
I think this string 14733 doesn't describe these behaviors well. Overall, this string should be revised totally to be technically correct and understandable.
