[O] navigating org-clock-in recent work list

[Tory S. Anderson]

As per a recent discussion on the mailing list, I'm using the following to 
enable persistence and extended length of the clock history:

--8<---------------cut here---------------start------------->8---
;; Org clock-in
(org-clock-persistence-insinuate)
(setq org-clock-persist t)
;;; * Orgmode Modules
(add-to-list 'org-modules 'habits)
;; Number of clock tasks to remember in history.
(setq org-clock-history-length 35)  ; 1 to 9 + A to Z
--8<---------------cut here---------------end--------------->8---

It works great, with one annoying problem: now that I have a list that goes to 
M, it can be hard to figure out which shortcut goes to which item. I can think 
of two possible solutions:

1. Alternately highlight lines, or underline (spreadsheet/table style)
2. Preferably, since I use Helm, if there were simply an autocomplete prompt 
(like switch-buffer; no shortcut keys) this would actually be easiest.

Can I disable the special pop-up screen (i.e. `org-clock-select-task') and just 
use an shortcut-less autocomplete prompt (which, with helm will be 
facilitated)?
