# Formula Shortcuts

I have to type some formulas of this kind very often $$\mathrm{e}^{\beta \varDelta t}$$

Is there a way I can create some shortcut with collection of such formulas that I can easily access per click so that I don't have to copy-paste them all the time? Something like a favorites bar?

I'm using TeXstudio

\newcommand{\myFn}{\mathrm{e}^{\beta \varDelta t}}

Then you can simply use your short-hand command, in this case \myFn, in your document like so: $$\myFn$$.
• The OP might find your macro more useful if you took out the display mode math (the $$). Then he could use it inside math mode as part of an equation or expression. Also: $$ is no longer the best way to display math. – Ethan Bolker Sep 11 '16 at 12:02
