Is it possible to implement global autosubstitution in Mac OS, as in Textmate (from already existing text words)?

Question

macOS

In Textmate, when you press Esc, auto-completion loops through already typed words that begin with the same letters that are already entered. There is a similar function in some IDEs.
Is it possible to implement the same, but at the global level, in any edit field? And How?

Answer 1

I'm sure it's possible. In essence, this is not much different from punto switcher (although I think that punto simply controls what was entered from the keyboard and uses a dictionary). I would start by searching for "mac os automator". The next step is to write a program that will live in the background.

Answer 2

TextExpander ?

Answer 3

Interest Ask. It turns out you want to add a menu that will appear when you press esc.
Punto Swithcer is global and does input field manipulation, so I dare to guess what is real. But it would be good to do it in a different combination, because. esc is used in places.
You can make the application as an agent (there will be many advantages during implementation).
