I type the same things over and over again. I would like an offline app that would capture everything I type (emails, code, reports) and create a library of snippets -- or better yet templates -- that I could access via a shortcut or a key combo.

For example, it would automatically recognize the five different email signatures I type often and make them accessible by typing, say, ”xxsig” followed by pressing TAB to cycle through the five signatures. I would also want it to learn how I write docstrings and generate templates that I could access via another keyword.
