I want to slide a label so I use this TeX code.
\xymatrix{A\ar^(.25){f}[r] & B}
Using directly this code as latex in LyX works, but I want to do the same thing in equations environment in LyX, what LyX is doing is putting all the (.25){f} part as superscript
\xymatrix{A\ar^{(.25){f}}[r] & B}
How ...
