If your interest is simply a macro-like feature to generate dates (or anything for that matter) most platforms leave those types of features to the keyboard macro tools.
For example, if I want “12-Nov-2019” inserted into my Airtable rich text field at the cursor, I simply type
\d which automatically expands to 12-Nov-2019 (even here in the community). I did not have to type the date - it just expanded instantly and I did not have to enter the space after it. As you can see - it works in Airtable:
I have dozens of macros that do many different things such as a code block here in the forum (i.e.,
\c) expands to:
One of the biggest advantages to keyboard-based templates is the speed that they can be dispatched and the fact that any approach that ties these macros to the platform (such as Airtable) do not work in other realms where you also likely type a fair bit of content.
Keyboard macros tend to become an extension of your muscle reactions. As such, once you adopt something like Text Expander, you expect these subtle productivity enhancers to be omni-present. Indeed, any investment in a system that saves time should ideally work everywhere you use your keyboard.
Narcissism and Laziness (from here down)
Wherever I happen to be communicating with others, I tend to promote my services and skills. Here in the Airtable forum I often make mention of Airborne, a search technology that I frequently use to help Airtable clients with search solutions. To do that, I simply type \as and this is what pops out of my keyboard:
You might want to take a quick read of this whitepaper about fast full-text search indexing across Airtable tables, bases, and even multiple workspaces.
I also have a number of shortcuts for popular historical quotes in the forum such as this one from @Chinara_James which I am always referencing - tapping out four characters (
/qcj) generates this quote block:
… but displays this actual quote:
