Go to the previous, next chapter.
For those users who live backwards in time, here is information about downgrading to
Emacs version 19.28. We hope you will enjoy the greater simplicity that results from the
absence of certain Emacs 19.29 features.
- This version doesn't support Windows NT, or the DEC Alpha.
- There is no support for editing formatted text. The text formatter TeX does a much better job of formatting
than any formatted text editor; we recommend you learn
to use it.
- C-Mouse-2 now runs the menu for setting the default font.
- F1 is no longer an alias for the Help key; you must actually type C-h
if you want help.
- Integers and buffer sizes are limited to 24 bits on
most machines. But as memory gets more expensive, you won't want to edit such large files
any more.
- There are no indirect buffers, so you can only display one view of an outline.
Meanwhile, the prefix key for Outline minor mode is now C-c C-o.
- When you are in Transient Mark mode, incremental
search always deactivates the mark.
- Dynamic abbrev completion
has been eliminated in 19.28, and some of the other dynamic abbrev
customization features are also gone.
- In Dired, Occur mode, Compilation
mode, and other such modes, you must use C-c C-c to select the item point is on. RET won't do it.
- M-x buffer-menu now displays the menu buffer in another window.
- The VC (version control) package no longer supports CVS or selecting branches other than the principal branch.
- There is no
recover-session command; if
Emacs crashes, you simply have to remember which files you were editing before the crash,
and use recover-file on the individual files.
- In Emacs Lisp mode, C-M-x now lets
defvar operate as it usually
does---setting the value of the variable only if it
has no value yet. Use ESC ESC to evaluate a Lisp expression, instead
of M-:.
- GNU-standard long option names are not supported.
(Real hackers prefer the shorter single-dash names, to save typing.) All the initial
options must come before all the action options, and whatever initial options you use must
appear in this order: -t, -d, -nw, -batch,
-q or -no-init-file, -no-site-file, -u
or -user, -debug-init.
