Probably the most simple way to set the opacity of GeoMarkers is with an undocumented usage of its "Color" parameter. It appears to support Directives, so the opacity can be set the following way: GeoGraphics[{GeoStyling["OutlineMap"], Opacity[.5], Polygon[Entity["Country", "Italy"]], GeoMarker[Entity["City", {"Rome", "Lazio", "Italy"}], "Color" -&...

For an example, InternalRadicalMemberQ[x y, {x^2 y, x y^3}] (* True *) which means that $x y$ belongs to the radical of the polynomial ideal generated by $x^2 y$ and $x y^3$. The method used to obtain the result is effectively Property 3 in the Gröbner Bases documentation, see http://reference.wolfram.com/language/tutorial/ComplexPolynomialSystems.html....

Citing this 1996 year MathGroup post by Dave Wagner, A similar function, Continuation[n], is called to format the character at the beginning of continued lines. So, for example, the definition Format[Continuation[n_]] := StringForm["(`)",n] would place a line number inside of parentheses on the second and subsequent lines of a multi-line ...

After a quick Google search I came across this, which provides a description. Translation: Continuation[n] is the result at the beginning of the nth line in a multiline printed Expression. The default value of Continuation is either the string " " or the string ">". The value of Continuation is can be changed with the command Format[Continuation[n_]]:=...

\[Continuation] is also the name of the special character used to indicate that input should be interpreted as continuing in the next line, or to break output too long for the current window. I suspect Continuation[] to be the operator form of that infix symbol. On second thought, I suspect that the formatting references you found are linked to special ...
