If you hold a section or block button to enter edit mode for the block or section, you just press Lock to lock/unlock that block or section.
If you are not in edit mode for a block or section (like when you press the Exit button), you can press and hold the Lock button. While holding it, all locked blocks/sections are lit up. If you want to lock additional ones, you press that button while continuing to hold Lock.
For your purposes, load the rig, hold lock, and while continuing to hold it, press Stomps and Effects. Then let go of lock - all stomps and effects are locked and you can load other rigs with those stomps/effects brought over
Thanks for that thorough explanation. Now I really get it.. This is what I really was trying to do. The other method I can lock that section only. So it's more difficult to say move stomps pre and effects post all at once.. This thing is so flexible and I'm still learning new things continuously
