Starting with version 1.5, Texpad makes it easy to insert regularly used blocks of text into your document. Texpad ships only a small number of helpful snippets and misses some I often use. Feel free to contribute and extend my small collection.
Some of the snippets require the usage of additonal packages in LaTeX:
Copy the snippets to ~/Library/Application Support/Texpad/Snippets.
The snippets are released under the CC BY-SA 4.0 license. See the license text for additional details.
