Step 1
Click the "Menu" button and then select the "Show Numeric Keypad" option. To hide it select the "Hide Numeric Keypad", which replaces the first option after it has been enabled.
Step 2
Use the Numeric Keypad to enter the session code, then click the "Join" button.
Note: The button in the bottom left serves as an alternative for the "Delete" button.
