How to reproduce

Load Macro "Auto-correct multiple capital letters" from macro repository
Create an new document (quick start wiz), a simple two liner is sufficient

\begin{equation*}
    \frac{1+1+1+1+1+1+1+1+1+1}
    {\frac{1+1+1+1+1+1+1+1+1}
    {\frac{1+1+1+1+1+1+1+1}
    {\frac{+1+1+1+1+1+1}
    {\frac{1+1+1+1+1+1}
    {\frac{1+1+1+1+1}
    {\frac{1+1+1+1}
    {\frac{1+1+1}
    {\frac{1+1}
    {1}}}}}}}}}
\end{equation*}

As an example add multi cursors before each but the first frac to change frac to dfrac. Enter d (use strg+alt+cursorDownArrow):
