How to change the hotkey on the keyboard to control the mic

Dragon has default keyboard shortcuts (hotkeys) to control the microphone.
Here's how to change the defaults to other keys, if the default keys don't suit.

Go to Dragon Bar / Tool / Options / Hotkeys
You can assign keys for toggling the mic between on and off, and between sleep and on.
To assign a key for toggling the mic between sleep and on, click on 'Microphone sleep /on'
Click Edit
Physically press the key you wish to use as the hotkey (make sure it isn't a key you need for another purpose. The Pause key is a good one because you won't need it for anything else)
Click OK
Click Apply
Click OK

Follow the same process to assign a key for Microphone on/off
