Text Snippet Question -

Well, you could use InCopy which has a text macro feature. That would likely be the easiest solution.

You can use the automatic correction feature that you can find in the preferences.

you just have to choose a kind of shortcut, a succession of signs in the mispelled field and insert the phrase in the correction field. Each time you will type this “shortcut” the correction will automatically be inserted in your text.

In my exemple, I have choosen “phr1” but it could be anything (that you don't use for real in the text).

I'm sure it could be scripted but I'm not a scripter. I'm on a Mac and I'd use Preferences/System Settings > Keyboard > Text Replacements.
