I opened BasicMath Palette.nb in a text editor and located the corresponding entries for those two buttons to be: RowBox[{ SuperscriptBox["\[InvisiblePrefixScriptBase]", "\[Placeholder]"], "\[SelectionPlaceholder]"}] RowBox[{ SubscriptBox["\[InvisiblePrefixScriptBase]", "\[Placeholder]"], "\[SelectionPlaceholder]"}] The \[InvisiblePrefixScriptBase] is documented in the Documentation Center on the page ref/character/InvisiblePrefixScriptBase as a "Mathematica character". Evidently, as others have noted, one cannot use the combinations shown as is from the palette in order to create a legitimate symbol. (Perhaps there's some way, though, to include it in a larger construction in order to create a symbol. I looked in the Notations package and didn't directly see a way with Symbolize there.) However, a Text cell definitely can accept such a thing, e.g., with x as the Placeholder and y as the SelectionPlaceholder.
