{title2=$f(\sup A)=\sup f[A]$}

A monotone map preserving suprema of nonempty <directed sets>. Between pointed domains it need not send bottom to bottom. The pointwise directed supremum of a directed family of such maps is again Scott continuous: interchange the two directed suprema in $\sup_f\sup_{x\in A}f(x)$.
