I got an email today from Text Expander that last month I saved four hours of typing by using short snippets that expand on my Mac. Most of the snippets are for replies at work, but some are for personal.
A few examples:
ddeexpands for my personal email address
hhomeexpands for my home address
llogasks for a WooCommerce customer to send log in details to their site
ccodetells customers that we do not support custom code
- and I have a ton that point people to specific products of ours
