When to use it
Use it when you have something relevant and there's a natural pause, or when the topic is about to move on without your input. You're not asking for permission; you're signaling that you're about to speak, which gives people a beat to make room.
Example
You: “I'd like to add one point before we move on. The vendor contract renews in June, so timing matters.”
Lead: “Good to know. Let's factor that in.”
In an email or Slack message
On a video call, use the raise-hand feature or type “I'd like to add one point when there's a moment” in chat. It gets you in the queue without talking over anyone.
