		    NEW FEATURES OF TRN 1.0 vs RN 4.3

New commands (article level)
	t		display a map of the thread's article tree.
	[, ], {, }	move around in the article tree
	J		junk an entire thread of disucussion regardless of
			subject changes.
	T		put the entire thread of discussion in the KILL file
			(as opposed to the current subject).
	<, >		move between threads of discussion
	U		mark some articles as unread again (choose from
			the current thread, subthread, selected threads, or
			all articles).
	e		extract a shar or uuencoded file.
	:		execute a command on all the selected threads/articles

New commands (newsgroup level)
	+		enter a newsgroup through the thread selector.
	U		enter a newsgroup through the "set unread" prompt.

New commands (thread selector)
	[...lots...]	use the thread selector to quickly browse the subjects
			and/or authors of articles and select only the ones
			that you want to read.  You can read each one as
			soon as you select it, or select them all at once.
			Use the 'h' command to see a command summary, or read
			the man page for more details.

New header display:	we display a subset of the thread's article tree in
			each header.

New display ordering:	the articles appear in their reply order.

New switches (default may be on, use +x/+X to turn them off)
	-x		turn on threaded extensions.
	-X		use thread selector to enter a group.

New magic (use +H to turn them off)
	-Hfrom		displays only the commented portion of the user name.
	-Hdate		displays the date in local time.

New environment variables
	EXSAVER		shell command that starts an extraction.
	SELECTCHARS	the character set to use to select threads
			(default:  abcdefgijlorstuvwxz1234567890).
	UNSHAR		the unshar program to use (default /bin/sh).
	REPLYTO		the value to use for the "Reply-To:" header, if
			needed.

New mode
	%m=t		when in the thread selector

New % interpolations
	%#		keeps an incremental count during a multi-file save,
			extract, etc.  ":s part.%#"
	%e		the last command executed to extract an article.
	%E		The number of extra (unselected) articles, not
			counting the current article (if selected).
	%U		same as before (number of unread articles, not counting
			the current one) but if selections are on, only counts
			selected articles.
	%Z		The number of selected threads.

Macros and Keymaps
	When defining macros, make sure you don't define something that
	will conflict with the selection characters in the thread selector.
	An easy way is to exclude the thread selector with a mode test:

		f	%(%m=t?f:|mail smith\n)

	Also, if you want to use one of the selection characters as a
	command in the thread selector, be sure to exclude it from the
	list of selection characters in SELECTCHARS (you can define this
	with -ESELECTCHARS=abc123 in your .rninit file).

Miscellaneous
	...and much, much more! (including various bug fixes!)
