Change shortcut of subscript from 'ctrl+_' into 'ctrl+l' failed?

I want to change the shortcut of subscript from ctrl+_ into ctrl+l. I find the KeyEventTranslations.tr file, successfully change superscript from ctrl+6 into ctrl+h. But when I do the same thing to subscript, i.e., comment the original code, change it into mine ctrl+l by

Item[KeyEvent["l", Modifiers ->{Control}],  "Subscript"]

but when I reopen Mathematica, the subscript does not work. Why didn't it work?

I tried to change the binding, find that ctrl+q works well, it seems that ctrl+l has been used by something else, how can I change ctrl+l to what I want it to?

Solution

  • First search the shortcuts list of mathematica, find that its original function is Input from Above. So we need to comment the code below from MenuSetup.tr file

    MenuItem["&Input from Above", FrontEnd`DuplicatePreviousInput[After], MenuKey["l", Modifiers->{"Control"}]]
