[NTG-context] How to adjust the sistance between a letter and subscript

Hi Jeong, you can always adjust the space between characters like this: \startformula T_X    \quad {\cal T}{\hskip-1mm}_X    \quad      T_Y    \quad {\cal T}{\hskip-1mm}_Y \stopformula I am not sure about side effects, but seems to work fine at least in this example.
