This is probably a lawyer thing but I often find myself adding signature lines to the bottoms of documents, particularly contracts. Something like this.

Dated: November __, 2014 ________________

I was doing this the other day for about the millionth time in my 21-year career as an attorney when it occurred to me I could automate this with TextExpander. Here is my new snippet

The first bit:

Dated: %B __, %Y ____________________________

This creates a line with the date using the format of Current Month __, Current Year (e.g. November __, 2014). Then it tabs and and draws a line for the signature.

The second bit:

%key:tab%%key:tab%%key:tab%%clipboard

This repeatedly bangs the tab key and then dumps the contents of the clipboard.

The way I use this is to select the person's name from somewhere else in the document, copy it, and then fire off the snippet at the bottom. I use xsigline to trigger this snippet.

This is probably a lawyer-only thing but I do know a few lawyers read this site. Either way, you can download the snippet here.
