;;; Synched up with: Not in FSF

;;; Commentary:

;; This package aimed to bring popup menus to be more usable for
;; keyboard friendly and mouse unfriendly people like me.  On the one
;; hand I like popup menus, because they just perfect and easy
;; interface for selective task, but on the other hand I hate them,
;; because I need to find my trackball, click ugly buttons, twiddle
;; ball to access menu item.  This pretty annoys.  Also popup menus
;; are not available in console.  tpum.el package makes popup menu
;; inlined in buffer, or creates transient XEmacs frame with temporary
;; buffer, where menu will be inlined.  So this makes possible to
;; control popup menus using keyboard and makes possible to popup
;; menus in console.  To start using tpum.el just include in your
;; ~/.emacs next:

;; To enable tpum globally:
;;    (require 'tpum)
;;    (tpum-global-mode 1)

;; Or if you don't want tpum to be enable globally (default) do
;; something like:
;;    (autoload 'tpum-minor-mode "Toggle tpum minor mode." t)
;;  And then enable tpum minor mode by `M-x tpum-minor-mode RET'.

;;; Customization:

;; To change tpum styles use:
;;    (setq tpum-cstyle 'tpum-style-pseudo)
;;    (setq tpum-menu-type 'inline)
;; Best menu redering done if you are using fixed width fonts with
;; pseudo-graphic characters and 'tpum-style-pseudo as tpum style.
