Copilot++ preview key seems to accept the edit?

I am on a mac. When i see a suggest edit from copilot++, and hit the option key, it seems to just accept the edit (same functionality as the tab key). It does not preview the edit.

Some changes were made to Copilot++. You should already see the suggested change next to your code, so you don’t have to hit a key to preview it anymore.
