Consider the following math mode notation: \bar{\Delta)}

Is there anyway I make this simpler. Say I want to type \bd and get \bar{\Delta)}. How can I do that?

  • I know this is a question that must have been asked 1000 times in all kinds of places, but I simply don't know what to google – k.dkhk Jun 21 '19 at 21:20
  • You could use \newcommand{\bd}{\bar{\Delta)}} but really shouldn't. Use keyboard short cuts instead, your collaborators will appreciate it. –  Jun 21 '19 at 21:23

Here my same proposal of the best user @marmot. You can create a specific short macro.

enter image description here

\documentclass[a4paper,12pt]{article}
\usepackage{amsmath,amssymb}

\newcommand{\bd}{\bar{\Delta}}

\begin{document}
\[\bd\]
\end{document}
