Options - Options ~ Control

Enable foot pedal controller
Check this box if you intend to use a controller.

Active controller
Shows the type of controller that is configured, if any, and it's status.

Properties
Shows static properties of the active device, such as the company, model, and interface. Also allows changes to some configuration options, such as which port to use for a controller that connects to a serial port.

Command map / test
Shows a list of the active controller's buttons or pedals.

The first column shows the name of the button or pedal.
The second column shows the Express Scribe command that will be run when this button or pedal is pressed.
Commands marked with a "*" are affected by the "Tap lock" option, below.
The third column is used to test the controller configuration by showing if each button or pedal is currently pressed.

Click "Change a Command" to bring up a dialog that allows you to change the command performed by a button or pedal.

Click "Reset to default commands" to reset the command mappings for each button or pedal to their original state.

Tap lock
Any command marked with a "*" in the "Command map / test" dialog can be run for variable duration. The command will start when the mapped button or pedal is pressed. Change the tap lock options to configure when the command will stop.

When tap lock is disabled, the command will always stop when the button or pedal is released.
When tap lock is enabled:
- If unlock time-out is disabled: The command will always continue after the button or pedal is released, and will stop on the next press.
- If unlock time-out is enabled: If the button or pedal is released quickly then the command will continue until the next press. However, if the button or pedal is held longer than the time-out then tap lock is ignored and the command will stop when the button or pedal is released.
