Here's the tutorial which shows how to create mouse bits and rout tabs.

Here's the notes from my tutorial:

ADD MOUSE BITES and Panelize:

1. Use Auto Rout PCB to automatically generate the Rout border.

Note: Select the corner where you wish to have the Rout Path Start (it really doesn't matter but I prefer the upper-left corner)

2. Insert Tabs (choose the one with mouse bites).

3. Select Tab location.  (I like to set snap to "mid-point" and selec 4 sides to add tabs)

4. Generate Panel.

Note:  To make more tightly packed, set the PCB spacing to the rout tool size.  In this case it's 90 mils. 

5. That's IT!
