Preferences

AM Rig Menu keeps its few settings in one file, pref.json, inside its own folder:

AM_Tools/scripts/Am_rigMenu/pref.json

Key	Holds
markingMenu_key	the hotkey, e.g. ctrl+s — set from the hotkey dialog
updates	the update settings: automatic checks, skipped version, the last check

Reinstalling or upgrading keeps this file, and upgrading from 0.2.x carries the old install's hotkey over. You should not need to edit it; delete it to go back to defaults.

Kept by Maya

Setting	Where
The hotkey binding	Maya's hotkey set (see First steps)
Which stored pose Switch pose goes to next	the Maya option variable goto_rigPose__ov
