In the last version of Mathematica (12.2), some genius on Wolfram thought that is was a good idea to change the keyboard shortcut Ctrl+4, that have been there for years, so now users get a (broken) box to input TeX (doesn't work in my system) instead of an underscript.

It's possible, but really annoying, to enter underscripts entering an overscript (Ctrl+7) and switching to underscript (Ctrl+5), then deleting the overscript.

This change also breaks the documentation of Underscript, by the way.

Is there a way to configure the notebook and remap the shortcut to the older one?

In Mathematica 12.2 the way to enter underscripts is Ctrl+Shift+, (comma). At least on macOS.

    $\begingroup$ @jjagmath This is mentioned in Incompatible Changes since Mathematica Version 1, but WRI seems to forget to update the document page of Underscript $\endgroup$

  • $\begingroup$ @jjagmath Just found the document of Underscript has been updated, not quite sure when it happened, though. $\endgroup$
