For typesetting in italics LaTeX provides the command \textit{<some text>} and also the declaration \itshape used as {\itshape <some text>}.

There is also the command \MakeUppercase{<some text>}. I would like to be able to have a declarative form like {UppercaseIt <some text>} but I have been unable to produce one. I tried to find the definitions of textit and \itshape in the hopes of doing something similar in transforming one into the other. I tried texdoc article but that didn't have the definitions so they must be somewhere else.

there is no way to do this in general – David Carlisle Sep 22 '21 at 17:16

if you can guarantee the end of the group is a literal } not a table cell or end of environment etc then it's posssible to fake something. – David Carlisle Sep 22 '21 at 17:17

@DavidCarlisle I had forgotten that I had asked the question before but it was several months before there were any answers and I was not notified of them. Should I delete my question? – Peter Wilson Sep 24 '21 at 17:41
Peter, no harm done, this one is closed as duplicate so it doesn't really matter you could delete or leave it – David Carlisle Sep 24 '21 at 22:37
