You can control the recording of sound on a topic by clicking the Set Recording Options link on the Name Your Topic page and setting the following options:
Record sound with topic: By default, the Recorder is not set to record sound with a topic. Click this option to enable sound recording. This setting can be overridden on the Recorder at the beginning of the recording session.
Pause Sound recording key: By default, the Recorder uses the PAUSE key to pause sound recording for a topic. If the PAUSE key is difficult or inconvenient for you to use, you can change the Recorder sound pause key. You can use any of the function keys, or a combination of any of the function keys (F1 through F12) and the ALT key, CTRL key, and/or SHIFT key.
If you change the Sound pause key, you should select a key or key combination that is not used in the target application for another purpose. For example, pressing the F1 key in some applications opens a Help window. Therefore, for those applications you would not want to use the F1 key to pause sound recording.
