How can I disable smallcaps within \textsc{}?
I would like to be able to disable/toggle smallcaps on a local level so that something like \textsc{o\textrm{open}mp} looks like \textsc{o}open\textsc{mp}. The reason for not doing the latter is to try to make use of the glossaries package with the smallcaps option for abbreviations. This automatically does the outer \textsc{} wrapping.
\textsc{o\textup{open}mp}should work. – egreg Oct 10 '11 at 22:04
