# How can I adjust the span between under bar and formula

### LaTeX:

$\alpha =\underset{\square }{\overset{\square }{\lim \sup \sqrt[n]{\left|a_n\right|}}}$

-

Then just highlight the placeholder under the formula and press Ctrl-$\uparrow$ two or three times, according to your taste. Each key press will nudge the placeholder (or superscript) up toward the formula.
