It needs to be a little more self-documenting; for instance, it should say how to switch to another block. It has a lot of commands: (define-key ubb-mode-map (kbd "") #'ubb-describe-codepoint-briefly) (define-key ubb-mode-map (kbd "D") #'ubb-describe-codepoint) (define-key ubb-mode-map (kbd "f") #'ubb-forward-codepoint) (define-key ubb-mode-map (kbd "b") #'ubb-backward-codepoint) (define-key ubb-mode-map (kbd "n") #'ubb-next-set) (define-key ubb-mode-map (kbd "p") #'ubb-prev-set) (define-key ubb-mode-map (kbd ">") #'ubb-next-set) (define-key ubb-mode-map (kbd "<") #'ubb-prev-set) (define-key ubb-mode-map (kbd "N") #'ubb-select-set-by-name) (define-key ubb-mode-map (kbd "G") #'ubb-browse-group-by-name) (define-key ubb-mode-map (kbd "C") #'ubb-browse-block-by-codepoint) (define-key ubb-mode-map (kbd "+") #'text-scale-increase) (define-key ubb-mode-map (kbd "-") #'text-scale-decrease) (define-key ubb-mode-map (kbd "*") #'ubb-reset-text-scale) (define-key ubb-mode-map (kbd "g") #'ubb-redraw) (define-key ubb-mode-map (kbd "q") #'ubb-quit) and it isn't obvious to me what they all do. Many of the characters don't display on my console, Have we got a way to tell, in Emacs Lisp, whether a certain character code can actually display? I think there is one. Could this use that to show something meaningful, for characters that can't really display? For instance, a sequence of 2 or 3 characters that somehow stands for the real character? For instance, the sequence << could stand for «, and the sequence i-. could stand for dotless i. -- Dr Richard Stallman President, Free Software Foundation (gnu.org, fsf.org) Internet Hall-of-Famer (internethalloffame.org) Skype: No way!
