Hmm IMO that replace is not possible in mathed insets without greater
rewrite of lyxfind.C as it assumes that the selection is found inside
a LyXText structure, which it seems mathed insets do not have.
This is mainly what lyxfind.C does for a single replace if some text was
already found and is selected (but have a look at that file).
bv->hideCursor();
bv->update(bv->getLyXText(), BufferView::SELECT|BufferView::FITCUR);
bv->toggleSelection(false);
bv->getLyXText()->replaceSelectionWithString(bv, replacestr);
bv->getLyXText()->setSelectionOverString(bv, replacestr);
bv->update(bv->getLyXText(),
BufferView::SELECT|BufferView::FITCUR|BufferView::CHANGE);
++replace_count;
So you see that the substitution is actually done by the function
LyXText::replaceSelectionWithString(...)
