-3.10: Text Selections
-=====================
-
-Q3.10.1: How can I turn off or change highlighted selections?
--------------------------------------------------------------
-
- The `zmacs' mode allows for what some might call gratuitous
-highlighting for selected regions (either by setting mark or by using
-the mouse). This is the default behavior. To turn off, add the
-following line to your `.emacs' file:
-
- (setq zmacs-regions nil)
-
- Starting with XEmacs-20.2 you can also change this with Customize.
-Select from the `Options' menu `Customize->Emacs->Editing->Basics->Zmacs
-Regions' or type `M-x customize <RET> editing-basics <RET>'.
-
- To change the face for selection, look at `Options->Customize' on
-the menubar.

-
-Q3.10.2: How do I get that typing on an active region removes it?
------------------------------------------------------------------
-
- I want to change things so that if I select some text and start
-typing, the typed text replaces the selected text, similar to Motif.
-
- You want to use something called "pending delete". Pending delete
-is what happens when you select a region (with the mouse or keyboard)
-and you press a key to replace the selected region by the key you typed.
-Usually backspace kills the selected region.
-
- To get this behavior, add the following line to your `.emacs':
-
- (turn-on-pending-delete)
-
- Note that this will work with both Backspace and Delete.

-Q3.10.3: Can I turn off the highlight during isearch?
------------------------------------------------------
-
- I do not like my text highlighted while I am doing isearch as I am
-not able to see what's underneath. How do I turn it off?
-
- Put the following in your `.emacs':
-
- (setq isearch-highlight nil)
-
- Starting with XEmacs-20.2 you can also change this with Customize.
-Type `M-x customize-variable <RET> isearch-highlight <RET>'.
-
- Note also that isearch-highlight affects query-replace and ispell.
-Instead of disabling isearch-highlight you may find that a better
-solution consists of customizing the `isearch' face.

-Q3.10.5: The region disappears when I hit the end of buffer while scrolling.
-----------------------------------------------------------------------------
-
- This has been fixed by default starting with XEmacs-20.3.
-
- With older versions you can turn this feature (if it indeed is a
-feature) off like this:
-
- (defadvice scroll-up (around scroll-up freeze)
- (interactive "_P")
- (let ((zmacs-region-stays t))
- (if (interactive-p)
- (condition-case nil
- ad-do-it
- (end-of-buffer (goto-char (point-max))))
- ad-do-it)))
-
- (defadvice scroll-down (around scroll-down freeze)
- (interactive "_P")
- (let ((zmacs-region-stays t))
- (if (interactive-p)
- (condition-case nil
- ad-do-it
- (beginning-of-buffer (goto-char (point-min))))
- ad-do-it)))

-Q4.0.1: How do I set up VM to retrieve mail from a remote site using POP?
--------------------------------------------------------------------------
-
- Use `vm-spool-files', like this for example:
-
- (setq vm-spool-files '("/var/spool/mail/wing"
- "netcom23.netcom.com:110:pass:wing:MYPASS"))
-
- Of course substitute your actual password for MYPASS.

+5.1: Emacs Lisp Programming Techniques
+======================================
+
+Q5.1.1: What is the difference in key sequences between XEmacs and GNU Emacs?
+-----------------------------------------------------------------------------
+
+ Erik Naggum <clerik@naggum.no> writes;
+
+ Emacs has a legacy of keyboards that produced characters with
+ modifier bits, and therefore map a variety of input systems into
+ this scheme even today. XEmacs is instead optimized for X events.
+ This causes an incompatibility in the way key sequences are
+ specified, but both Emacs and XEmacs will accept a key sequence as
+ a vector of lists of modifiers that ends with a key, e.g., to bind
+ `M-C-a', you would say `[(meta control a)]' in both Emacsen.
+ XEmacs has an abbreviated form for a single key, just (meta
+ control a). Emacs has an abbreviated form for the Control and the
+ Meta modifiers to string-characters (the ASCII characters), as in
+ `\M-\C-a'. XEmacs users need to be aware that the abbreviated
+ form works only for one-character key sequences, while Emacs users
+ need to be aware that the string-character is rather limited.
+ Specifically, the string-character can accommodate only 256
+ different values, 128 of which have the Meta modifier and 128 of
+ which have not. In each of these blocks, only 32 characters have
+ the Control modifier. Whereas `[(meta control A)]' differs from
+ `[(meta control a)]' because the case differs, `\M-\C-a' and
+ `\M-\C-A' do not. Programmers are advised to use the full common
+ form, both because it is more readable and less error-prone, and
+ because it is supported by both Emacsen.
+
+ Another (even safer) way to be sure of the key-sequences is to use
+the `read-kbd-macro' function, which takes a string like `C-c <up>',
+and converts it to the internal key representation of the Emacs you
+use. The function is available both on XEmacs and GNU Emacs.
+

+
+Q5.1.2: Can I generate "fake" keyboard events?
+----------------------------------------------
+
+ I wonder if there is an interactive function that can generate
+"fake" keyboard events. This way, I could simply map them inside
+XEmacs.
+
+ This seems to work:
+
+ (defun cg--generate-char-event (ch)
+ "Generate an event, as if ch has been typed"
+ (dispatch-event (character-to-event ch)))
+
+ ;; Backspace and Delete stuff
+ (global-set-key [backspace]
+ (lambda () (interactive) (cg--generate-char-event 127)))
+ (global-set-key [unknown_keysym_0x4]
+ (lambda () (interactive) (cg--generate-char-event 4)))
+
+\1f
+File: xemacs-faq.info, Node: Q5.1.3, Next: Q5.1.4, Prev: Q5.1.2, Up: Miscellaneous
+
+Q5.1.3: Could you explain `read-kbd-macro' in more detail?
+----------------------------------------------------------
+
+ The `read-kbd-macro' function returns the internal Emacs
+representation of a human-readable string (which is its argument).
+Thus:
+
+ (read-kbd-macro "C-c C-a")
+ => [(control ?c) (control ?a)]
+
+ (read-kbd-macro "C-c C-. <up>")
+ => [(control ?c) (control ?.) up]
+
+ In GNU Emacs the same forms will be evaluated to what GNU Emacs
+understands internally--the sequences `"\C-x\C-c"' and `[3 67108910
+up]', respectively.
+
+ The exact "human-readable" syntax is defined in the docstring of
+`edmacro-mode'. I'll repeat it here, for completeness.
+
+ Format of keyboard macros during editing:
+
+ Text is divided into "words" separated by whitespace. Except for
+ the words described below, the characters of each word go directly
+ as characters of the macro. The whitespace that separates words is
+ ignored. Whitespace in the macro must be written explicitly, as in
+ `foo <SPC> bar <RET>'.
+
+ * The special words `RET', `SPC', `TAB', `DEL', `LFD', `ESC',
+ and `NUL' represent special control characters. The words
+ must be written in uppercase.
+
+ * A word in angle brackets, e.g., `<return>', `<down>', or
+ `<f1>', represents a function key. (Note that in the standard
+ configuration, the function key `<return>' and the control key
+ <RET> are synonymous.) You can use angle brackets on the
+ words <RET>, <SPC>, etc., but they are not required there.
+
+ * Keys can be written by their ASCII code, using a backslash
+ followed by up to six octal digits. This is the only way to
+ represent keys with codes above \377.
+
+ * One or more prefixes `M-' (meta), `C-' (control), `S-'
+ (shift), `A-' (alt), `H-' (hyper), and `s-' (super) may
+ precede a character or key notation. For function keys, the
+ prefixes may go inside or outside of the brackets: `C-<down>'
+ == `<C-down>'. The prefixes may be written in any order:
+ `M-C-x' == `C-M-x'.
+
+ Prefixes are not allowed on multi-key words, e.g., `C-abc',
+ except that the Meta prefix is allowed on a sequence of
+ digits and optional minus sign: `M--123' == `M-- M-1 M-2 M-3'.
+
+ * The `^' notation for control characters also works: `^M' ==
+ `C-m'.
+
+ * Double angle brackets enclose command names: `<<next-line>>'
+ is shorthand for `M-x next-line <RET>'.
+
+ * Finally, `REM' or `;;' causes the rest of the line to be
+ ignored as a comment.
+
+ Any word may be prefixed by a multiplier in the form of a decimal
+ number and `*': `3*<right>' == `<right> <right> <right>', and
+ `10*foo' == `foofoofoofoofoofoofoofoofoofoo'.
+
+ Multiple text keys can normally be strung together to form a word,
+ but you may need to add whitespace if the word would look like one
+ of the above notations: `; ; ;' is a keyboard macro with three
+ semicolons, but `;;;' is a comment. Likewise, `\ 1 2 3' is four
+ keys but `\123' is a single key written in octal, and `< right >'
+ is seven keys but `<right>' is a single function key. When in
+ doubt, use whitespace.

+
+Q5.1.4: What is the performance hit of `let'?
+---------------------------------------------
+
+ In most cases, not noticeable. Besides, there's no avoiding
+`let'--you have to bind your local variables, after all. Some pose a
+question whether to nest `let's, or use one `let' per function. I
+think because of clarity and maintenance (and possible future
+implementation), `let'-s should be used (nested) in a way to provide
+the clearest code.
