Sorry I didn;t write an example Here's the issue - I have variables such as P_AB - that is P and AB as an index. Mathematica writes \text{} whenever it sees the AB which is unwanted - I want the whole thing to appear in italic form. May be it's a standard convention I'm not really sure, but it just looks ugly and I looked in some math books and saw it all written in italic font there. So is there a way to turn this off?
