Thank you too! Actually, I have a question about "var". "var" does not have an effect in my config, but "tab" does. I believe it is related to lazy loading, but I don't know how to deal with it. My config only contains the code snippet you posted above and nothing else.

(kbd-map (:mode in-math?) ("1 var" (insert `(rsub "1"))))

The above code snippet works fine with either "1 var" or "1 tab".

Hi,

I am wondering if there is a convenient way to turn the numbers after a symbol into a subscript. For example, now I have the following keybinding in my config:

("a 1" (insert '(concat "a" (rsub "1"))))

And then copy and paste for other characters and subscripts. I hope there is a better solution than copy/paste. My current idea is to set up a keybinding for "1 tab", "2 tab", etc, so that the tab will turn the number into a subscript of the previous symbol. But I don't quite know how to move in the document tree (or directly manipulate it). I read the document "Programming routines for editing documents" but still have no idea, like how can I get the tree representing the symbol before the cursor.

Thanks!

Zhuyang
