A catalogue of hot keys 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 hot keys in the hot key catalogue are stored in the following formats:
| Where: | Means: | 
|---|---|
| <component> | The module containing the hot key. | 
| default | The keystroke that is currently in use. | 
| factory | The Autodesk factory default. | 
| butt | A button hot key. | 
| func | A non-button function hot key. | 
User-modified hot keys are stored in a separate file: default.<component>.butt.hotkey.user. This file is loaded after the system hot key file, default.<component>.butt.hotkey. Entries in the user-modified hot key file replace the system hot key entries, with the exception of cloned hot keys, which are duplicated.
