I fiddled around with "font insets" for mathed lately, and by now I am fairly convinced that this is the Right Thing to do. It is much more "logical Markup", it is basically what LaTeX does, and it is what Docbook does (if that's what José said). I don't think it is what "conventional word processors" do, but to be honest, I don't care. I don't know how big a change this would be for 'main LyX', as it is already such a big change for mathed that I won't try to sneak it into 1.2.0 [and new insets are really easy in mathed nowadays...] The change, however, _is_ nice: It's about 200 lines _less_ code right now and it removes almost all font related hacks (like passing a font change through macro arguments...). So the change just 'feels good'. > ANother candidate would be Paragraph::insertChar, which is called a > lot during parsing (and maybe other places) for inserting at the end > of paragraph.

Just push_back() the char to the container... - For the 'speed of string comparison matter': Somewhere in one of my older projects I had some class wrapping a 'const char *' and a hash values of the string for exactly that purpose. I seem to remember a speedup of four or five or so. So if this is really crucial, I can dig this out (or re-invent the wheel which is probably better for the stomach contents than looking at six years old code...)
