I will probably get blasted for this because this may be common knowledge to everyone but myself. I usually read instruction manuals and did with my SL2 but I don't remember this being in there.
On the SL2 if you hold down the middle button (the button in the middle of the wheel) this will act like a previous channel button and will take you back to the last channel you were listening too.
Example: If your listening to Howard 100 and were previously listening to Howard 101, just press and hold the middle button and the SL2 will jump back to the previous channel.
Again, 9/10ths of you are probably rolling your eyes and saying "no sh**" at this but I really somehow did NOT know about this.
