If `msg.payload` is not recognised as any of the above commands, it is treated
as a text message to be scrolled across the screen.
If the text is a single character, it will be displayed without scrolling. To
scroll a single character, append a blank space after it - `"A "`.</p>
The following message properties can be used to customise the appearance:
- `msg.colour` - the colour of the text, default: `white`
- `msg.color` - the colour of the text, default: `white`
- `msg.background` - the colour of the background, default: `off`
- `msg.speed` - the scroll speed. A value in the range 1 (slower) to 5 (faster), default: `3`
