One feature that I like in aText, my current text expander app, is the option to use the same keyword for multiple snippets. For example, I use ',mail' for all of my email addresses. Whenever I enter it, a small window pops up and I'm able to key down and up and hit enter to select which email address I want to use (Here is a GIF of that: http://tinyurl.com/y8k2ur7y). This saves me creating a unique keyword for each email address and try to remember it when I need to use them.
I don't believe Alfred, even with the latest v.3.4.1 update, has that feature. Am I mistaken? Perhaps there is a neat way to implement this function that I'm not aware of?
