How does audio crossfade work?

I am baffled as to how to get one audio track to fade into another.

Let's say I want to put "Paint it Black" first and then crossfade to "Pinball Wizard".  (Yeah, I'm really dating myself😀)   When I select crossfade I get a popup balloon:  "Cross Fade requires at least two audio tracks.  Please drag a second audio track here"  even if I've already got the second track in the timeline.  If I now drag "Pinball Wizard" to the end of "Paint it Black" it just leaves one after the other and there's no crossfade.  If I drag "Pinball Wizard" on top of "Paint it Black", it just splits "Paint it Black" in two and sits between the two parts.

There's an "Effects" box that pops up above the timeline with some controls, but nothing is labelled and I have no idea what the controls do.

Any help will be greatly appreciated.

If these are typical linked audio/video clips, a CROSSFADE video transition will also crossfade the audio.

If both clips do not have enough excess unused content (that is not be seen on the timeline) to accommodate the fade duration, and the OPTIONS | EDITING tab Video transition default setting is Ask Me, a prompt will appear...

If freeze is chosen, audio on the FROM clip will fade out and audio from the TO clip will fade in.  If overlap is the choice, audio will crossfade.

If the crossfade is to be applied to only the audio tracks, offset the two tracks.  Position the red-lined cursor where the fade is to begin, right-click either audio track and choose CROSSFADE.  Set a duration.  The audio tracks will then look like this.  Note the blue lines that show the fade...

Glad it made sense.

Be aware that using Overlap can result in a sync issue if audio is not linked to video, as the video will be slightly shortened while audio is unaffected.

If they ARE linked (a typical A/V clip), then both audio and video will be shortened.
