On-The-Go Playlist: what is it and how to use?

Question

I've read the notice on the iPod when you select the On-the-Go playlist but don't know what it does and how to best use it. I've tried to add a song to it by holding down the center button while the song was playing but don't know how to check to see if it's been added. When I go to the On-the-Go playlist in the menu I only get the text instructions. Can someone describe how to add, and remove, songs from it or tell me if you can and how to use it?

EDIT: BAH! I posted too slow... but there is still some information about saving and clearing in there
Its for making a playlist while your 'on the go'. So you click and hold the middle button the selected song (or album) should flash... Then you go into the playlist menu (music>playlists>on-the-go) and use it like any normal playlist...
When there's songs on the playlist it gives you the option to save or clear at the end of the song list, you select either one and it'll ask for conformation.
It works in both manually sync and auto sync mode. But if you have it on auto sync the play list will be created in iTunes...
So I'm not sure why you don't see songs in it after yo assign them to it, try sending a whole album and then music>playlists>on-the-go the album songs should be listed.
As for reasons to use it well maybe while out and about you realise that you want to hear from two artists at the same time, Radiohead and Bowie, in a shuffle mode. You could make it a on-the-go playlist. Or there's a few podcasts you want to hear in order... so you go down the list and assign them to on-the-go.
Some people use the On the go to note songs that need to be looked at in iTunes later, maybe because its too quiet, badly imported or they don't understand how such a bad song found its way onto the iPod.
Once you save it if you try and put more songs to it, 'on-the-go-1' will be created.
-hope this helps
