config-helm.el

;;; package --- Summary
;;; Commentary:
;;; Code:

(require 'helm-mode)
(require 'helm)
(require 'helm-grep)

;; ;;; needed to avoid UI slowness
;; (setq x-wait-for-event-timeout nil)

;;; Do not turn on helm-mode here - for some reason doing it as an init
;;; step causes tab-autocomplete to not work in find-file
;;; (helm-mode 1)

;;; This configuration needs to be done in the post-init for some reason
;;; I don't understand; again, doing it as part of the init.el code
;;; makes various things not work.
