Using keyboard text shortcuts in word I created some text "shortcuts" (well..not very short) in Keyboard. For example, when I type \alpha I get α, and if I type \sigma I get σ. While this works in almost everything on my computer, it doesn't work in Microsoft Office (e.g., Word and PowerPoint). I wonder if there is a way to make these shortcuts also work in MS Office. Thanks!
Unfortunately MS Office products live in the own world.

So to make the Alpha and Sigma words be replaced with Greek symbols you need to do following.

Open Word- Preference.

Now choose the Auto Correct

There is a field called Replace -With where you can now do that.

See this example:



Use same process for PowerPoint.
