I like using UltiSnips to easily write lengthy commands, when typesetting mathematical notes using Vim as a text editor for the LaTeX software.

For example, if I want to add an image to a document, the necessary full command to type this might be `\includegraphics[scale=0.5]{Image_file_name}`, which is a lot to type for image-heavy documents.

But with UltiSnips, I can write any shortcut (e.g. by typing `img` and pressing the `Tab` key or alternatively letting it auto-complete depending on my snippet setting), then the whole command is typed out: `\includegraphics[scale=0.5]{$1}$0`. My cursor would immediately be placed at the $1 position, and pressing the `Tab` key would take me outside to the $0 position, so I can keep typing.

It's simple and predictable for myself as a user to easily write the full command, whereas I predict that a solution that uses an large language model (LLM) for this context may add complexity without making the task easier for my purposes (though LLM-based software may be more useful in other contexts).
