One of the features I use regularly in TextExpander is date/time calculations. I use time stamps a lot, especially in OmniFocus to mark updates to specific actions:
A lesser known tip is to press the Left arrow key followed by the Right arrow key when you have started to type your snippet. This simple action will tell TextExpander that you do not wish for this abbreviation to be expanded. Whenever you type an abbreviation and interrupt it with cursor movement, TextExpander will disregard it.
When I’m creating my blog posts, I have to use a LOT of links. That’s because when I mention a particular application or software company, I think it’s only fair to provide a link to their product. They do so much to enrich our lives with the apps they create, the list I can do is point my loyal readers towards them.
