Hi,LaTeX allows the \sideset command to position superscripts and subscripts on the left side also. For example,\sideset{_a^b}{_c^d} M prints 'M' with 'a' at its lower-left, 'b' at is upper-left, and with 'c' and 'd' at normal subscript and superscript positions.Can this effect be invoked in LyX?
\sideset wants to be followed by an operator -- do you have a way to convince LaTeX 'M' is an operator? I get an error message when I try the above.
That said, \sideset{_a^b}{_c^d}\prod works in LyX -- the formula does not look right in the GUI (meaning that LyX will not translate \sideset into the appropriate visual effects) but the DVI/PDF output will be correct. (If you turn on instant preview for formulas, it will show up in the GUI as well.) Entering it is a bit finicky, but not too hard. Starting inside a math inset, the keystrokes are as follows (` indicates a space):
1. \sideset` (appears verbatim in the math inset -- should change font after the space is entered)
2. \{ (creates both opening and closing braces)
3. _a`^b`
4. (cursor out of the braces but stay inside the inset)
5. \{
6. _c`^d`
7. (cursor out of the braces but stay inside the inset)
8. \prod`
