Just 't' or 'C-c t'? What I can see both works:

(require 'nroff-mode)
(define-key nroff-mode-map "t" (lambda () (interactive)
(message "t pressed")))
(define-key nroff-mode-map "\C-ct" (lambda () (interactive)
(message "C-c t pressed")))
(nroff-mode) ; then try t or C-c t

My actual goal is to bind C-c t when in nroff mode to my command
ajg-preview-troff.  To isolate any of my code I have tried

emacs -Q -nw
(require 'nroff-mode)
(define-key nroff-mode-map "t" 'dired)
nroff-mode-map

The result is
 (keymap (116 . dired) ...)

But 116 is not "t"; it is down.

Where is my error?
thanks,
allan

But 116 (decimal) is t.

(IOW, 116 is the character `t'.  In Emacs Lisp, characters are natural numbers- but not all natural numbers are characters.)

Using `C-h v' to view a keymap is not very user-friendly.

A better way is to load `help-fns+.el' and then use `C-h M-k',
which is command `describe-keymap'.  It prompts you for the
keymap symbol - in this case, `nroff-mode-map', and then lists
the keys bound in that map, in a human-readable way.
