Before we get started, it's important that you are familiar with which Qwerty keys correspond to the Steno keys and which fingers should be used to press each key.
Use the below demo to get familiar with this. Click below and start pressing keys on your keyboard. Make sure you are using the correct finger for each key.
Note that the asterisk is usually pressed with the index finger of the right hand but you can use the index finger of the left hand if that is more comfortable.
