"Insert" Key on Mac to overwrite at text cursor???

I used to be a big time PC user; now mac keyboards don't have "insert" keys.

Normally I'd throw a live template or snippet hit "insert" and type over the --------------- line created to add some fancy comments.

Without the insert it moves the characters coming after it along with the cursor over to the right ... when I wanted to overwrite the character.
"Insert" used to be a handy way of toggling between text insertion modes on PC.  Now I'm wondering; how do I do this on a mac in IntelliJ?

Thanks,
