You can use any word you like so long as it contains one of the following:
         "from"
         "to"
         both "from" and "to"
         "and"
in upper or lower case. If you fancy adding some punctuation (e.g. a ":")
then feel free.

They are all valid.

Yep, any combination of tabs and/or spaces will work just fine.

Basically, write what you want and it will probably figure it out for you.
I'm not into strict syntax, just makes it harder to use.
