This will find (forwards or backwards) but preserve the existing selection. Presently if the current selection is a zero-width selection (i.e. caret) then we still preserve it. This might not be desired, but one could imagine “extend selection” used with a regular expression which use a look-around assertion (resulting in zero-width matches).
