in situ

Definition: (in SY-too, in SICH-choo) (Latin) In the original place.

I have always seen it as in situ.

In addition, words that people wish to be written in italics are generally
underlined if an italics function is not available.  If an underline
function is not available, you can use HTML coding: in situ to
specify you want a word/term italicized. Underlining, however, should be
your primary option.
