You will need to extract the file by right-clicking on it and selecting "Extract Here". It will immediately be minimized to your System Tray. This will open the Auspex window. This will start the shortcut creation process. It's crucial that you don't type a phrase that you use for other things, as the shortcut will get replaced any time it is used.  A common trick is to use HTML-style tags as the phrase. For example, if you are creating a shortcut for (ಠ益ಠ), you could type &rage; into the "Replace" field. The & and ; ensure that you won't replace a real word by accident. Click the "OK" button when finished. Space, Tab ↹, or ↵ Enter to make the emoticon appear. These are the default trigger keys. You can change them using the "Triggered by" menu in Auspex when the shortcut is selected.
