1. Optionally, create a Group.
2. Create a Knob
3. Add devices:
   1. Do this "by hand" if you know the PV. Eg YCOR:IN20:492:BDES (YC06)
   2. Do this by "drilldown" (which uses physics name). In the Editor:
      1. Select a model sequence: Eg BXG TO BX01. Note that sequences are in alphabetical order. That is on the fix list.
      2. Select a device "type". Note that the type names given are:
         1) SNS type names, which themselves use >1 name eg hcorr == dch == horrzcorr => X correctors.
         2) and also flattened hierarchy of types, eg type "dipole" includes hcorr and vcorr.
      3. Select a device name, by "physics name".
      4. Select FieldSet (not FieldRB). (issue: FieldRB should not be offered).
   3. Or calculate bump knobs
      1. Select a section of contiguous sequence of sections (a "combo sequence") Accelerator->Sequences
         BXG TO BX01 - BX01 to BX02 works.
      2. Knobs->(Make Horizontal Bumps | Make vertical bumps) Make Horizontal Bumps (Make Vertical Doesn't work, since it seems so many of our correctors are SLC!)
      3. For Horizontal Bumps: These setups were tested.
         1. Design Offset 3 (default) magnets - works (4 magnet doesn't work!)
         2. Design Angle 5 (default) magnets - works
         3. Live Offset 3 - works
         4. Live Angle 5 works - works
      4. For Vertical Bumps, select sections BXG to BX01 - QM15 to FV2
         1. Design Offset 3 (default) magnets - works, but they're mostly SLC magnets, so you can't connect and can't set them.
4. "knob" your knob with the arrows. There is no "SENSitivity" in the SLC multiknobs sense, but you can choose the digit to vary.
