If you want to copy the entire track, along with all items and fx, you can right click and save the track as a template in the track control panel. Make sure to tick your options for saving items and envelopes at the bottom in the save as dialog. Then, in the other project, load it from the track template by right-clicking also in the track control panel. I use this all the time if I need to move one tack to another. One thing to be aware of is the track timebase if the 2 projects have different tempos. Often, I'll save parent folders with whole sections as a template and open them in other projects. Hope this helps!
