OK... I'll try.
First thing is, you do this with a bus, not another regular track.
In the track view, you've got all your tracks at the top, and all your buses at the bottom. If you don't see the busses, there's a little square button to show / hide them.
By default, you should have two buses there, Master and Metronome. Hopefully your project is still like this.
In the area where the buses are, right click and select "Insert Stereo Bus".
Give this a useful name, like "Reverb", or whatever you're going to have on there. I'm going to assume it's a reverb for the purposes of this explanation.
As you'll see, buses have effects bins just like tracks do. Right click in the bin, and insert your reverb.
Open up the reverb, and make sure that if it
does have a wet / dry control, it's fully wet and no dry. As you say yourself, the dry signal is going to come from the original track.
Now go back to the original track's header (ie: not the bit with the audio data on the right, but the bit with the controls on the left).
Right click in there, and choose "Insert send". There'll be a list of all the places you can "send" a copy of the track singnal to. The "Reverb" bus we've just made will be on this list. Select it, and the send controls will appear in the track header.
The main control you're going to be concerned with is "Level". This is how loud the copy of the original signal going to the reverb will be. So this is effectively giving you your "wet" control.
The nice thing here is, you can send as many tracks as you like to this one reverb. This is CPU efficient, but more importantly, is good for making multiple sounds seem like they're in the same space.
