Text Blaze is a free Chrome extension of the “text expander” type. It allows you to create abbreviations that will automatically expand to other user-definable text. There are lots of these text expanders out there; I’ve tried a few, but none have provided the functionality and usability of Text Blaze for free.
For instance, I’ve set up a snippet that turns “/today” into [17.03.19].
There’s a bit of a programming interface so you can create quite complex substitutions, even in Google Docs too. And it connects to your Google Account, so install it once and it will “spread” to all your devices that support Chrome extensions automatically
If you’re looking for an easy way to make your Chrome browser work better for you, I suggest you look into this extension.
