Actually, it is documented:

?Ser
Ser(s,{v='x},{d=seriesprecision}): convert s into a power series with
variable v and precision d, starting with the constant coefficient.

?taylor.
taylor(x,t,{d = seriesprecision})

etc.

I just added it to ??prototype

This is not the complete prototypes!

This is for named flags, see ??ploth
