If I understand the question correctly, I don't think it's possible to do exactly what you want without extra steps. You could right click on the track and choose search > Locate in Library, and then play it.
You could use "Play More > Play Album Now" to get the whole album. You might also consider changing your Play Now preferences to "queue selected tracks next and play now", which will keep the whole search/library from being loaded, and keep the Now Playing list from being cleared each time you choose something new.
Once a track is playing, you can double click the title in the player to locate it in the library, if that helps.
