A catalogue of hotkeys is maintained for every user. If the user profile was created in the default home directory, the catalogue is found in /usr/discreet/user/effects/<user_name>/hotkey. If the user profile was created elsewhere, the catalogue is found in <user home directory>/hotkey. The hotkeys in the hotkey catalogue are stored in the following formats:
| Where: | Means: | 
|---|---|
| <component> | The module containing the hotkey. | 
| default | The keystroke that is currently in use. | 
| factory | The Autodesk factory default. | 
| butt | A button hotkey. | 
| func | A non-button function hotkey. | 
User-modified hotkeys are stored in a separate file: default.<component>.butt.hotkey.user. This file is loaded after the system hotkey file, default.<component>.butt.hotkey. Entries in the user-modified hotkey file replace the system hotkey entries, with the exception of cloned hotkeys, which are duplicated.
