Node-RED version: v0.18.7  
Node.js version: v8.11.2  
node-red-node-pi-sense-hat@0.0.15

I spent a lot of time trying to get the flip to work. The help says:

> Flip the screen
> 
> Format: F
> 
> axis must be either H or V to flip on the horizontal or vertical axis respectively.

So I tried `F<V>` and it didn't work. I tried `F<v>`, `f<v>`, `f<V>` - I tried `F(V)` and` F[V]`. I even tried digging thru the code but nothing worked till I finally tried `FV`.

My suggestion is to change the 'Node Help' for 'Rotate the screen' and 'Flip the screen'  
from:

> Rotate the screen
> 
> Format: R
> 
> angle must be 0, 90, 180 or 270.
> 
> Flip the screen
> 
> Format: F
> 
> axis must be either H or V to flip on the horizontal or vertical axis respectively.

to

> Rotate the screen
> 
> Format: R
> 
> angle must be 0, 90, 180 or 270.  
> `Example: R270`
> 
> Flip the screen
> 
> Format: F
> 
> axis must be either H or V to flip on the horizontal or vertical axis respectively.  
> `Example: FH`

and for 'Set the screen brightness' from:

> Set the screen brightness
> 
> Format: D
> 
> level must be 0 (low) or 1 (high).

to:

> Set the screen brightness
> 
> Format: D
> 
> level must be 0 (low) or 1 (high).  
> `Example: D1`
