  I've taken a cursory installation and inspection of icicles, then
  of ivy and then of which-keys.

  Icicles does not function in evil normal mode when key sequences
  are initiated. But that is without any customization. (shift-TAB
  is not recognized) When I invoke the icicles customization menu I
  see numerous options with the text "UNINITIALIZED, you should not
  see this."

  This tells me that Drew has anticipated issues and has remedies in
  mind.

  On the other hand, 'which-key works as advertised and from a
  cursory and initial experience is what I'm looking for in terms of
  key sequence completion.

  Ivy has not generated any opinions of mine thus far ...

  Having said that, I recognize that icicles is a very rich
  contribution which appears to have a wide variety of functionality. 

  Should Drew have the time to address the "UNINITIALIZED, you should
  not see this." messages and possible subsequent issues I would
  - given my time constraints - happy to see if we can get icicles
        key sequence completion working in evil normal state. Key
        sequence completion works like a charm and as advertized when I
        toggle C-z but not when the "normal state" is in effect.

  As always, I'm enthralled with what emacsen have contributed. 

  FYI: I'm on Alaska Daylight Time zone.

  cheers.
