Set edit points during recording

I have just started using Audacity for recording church services. I would like to record most of the service so that it can be burned to DVD (e.g. for older housebound folk with no internet access), but I would also like to be able to create a clip of just the sermon to put on our website. Rather than have to search for the start/end of the sermon during editing, is there any way that I can flag an edit point during recording at the start and end of the sermon, so that I can easily find them during subsequent editing?

Audacity 2.0.5 under Windows XP SP3

During recording (or playback), use Ctrl+M to create a “marker” (label).
Optionally you can enter text in the label.
Press ENTER to close the label text.

Tip: Have a practice with it before you need to use it during a service.

Thanks Steve, sounds ideal - I’ll give it a go.
