Metadata File

I am trying out the 4.4. beta version. I have set cue points on an audio track but cannot find anywhere the button to save the metadata file? Is this because things have changed since the 3.1 user manual or am I being stupid here? If the manual is out of date, how should I save cue points now?
Thanks for any help.

In the Properties dialog, it’s in the Export menu button at the bottom of the window.

If you want that button in the Cue Editor that pops up during PFL as well, you can turn it on in the config.

Thanks Torben, just what I needed.
