@sp 1
@strong{Q.} @emph{How do I hide #ifdef's in source files without
actually changing them?}

@strong{A.}  Use @code{hide-ifdef-mode} which supports hiding of ifdef
blocks without actually changing the file. In this mode @kbd{C-c @@
C-d} hides ifdef block and @kbd{C-c @@ C-s} shows it again.

@sp 1
@strong{Q.} @emph{How do I get more informations about the keybindings
of the currently active modes?}

@strong{A.} Type @kbd{M-x describe-mode}.

@sp 1
@strong{Q.} @emph{How do I get automatic syntax higlighting of my
custom types?}

@strong{A.} Use a package named @file{ctypes.el} which does exactly
that.

@sp 1
@strong{Q.} @emph{Is it possible to highlight dangerous syntax, just
like Borland JBuilder does it?} 

@strong{A.} Yes, use the @file{cwarn.el} package.

@sp 1
@strong{Q.} @emph{How do I easily customize Emacs faces/colors?}

@strong{A.} Use the @file{color-theme.el} package.

@sp 1
@strong{Q.} @emph{How do I set the taskbar Emacs identification string?}

@strong{A.} To your @file{.emacs} add a line like:
@example
(setq frame-title-format "%b (%m)")
@end example
which will display ``filename (mode)'' type of string in the
taskbar. Type @kbd{C-h v frame-title-format}  to get more info.

@sp 1
@strong{Q.} @emph{Can I make Emacs jump to the matching parenthesis
with @kbd{%} just like vi?}

@strong{A.} Yes, just add to your @file{.emacs} something like:
@example
;; Make the % key jump to the matching {}[]() if on another, like VI
(global-set-key "%" 'match-paren)

(defun match-paren (arg)
  "Go to the matching parenthesis if on parenthesis otherwise insert %."
  (interactive "p")
  (cond ((looking-at "\\s\(") (forward-list 1) (backward-char 1))
        ((looking-at "\\s\)") (forward-char 1) (backward-list 1))
        (t (self-insert-command (or arg 1)))))
@end example

@sp 1
@strong{Q.} @emph{Can I have words like FIXME, TODO, HACK or NOTE 
higlighted in documentation strings?}

@strong{A.} Yes, either use @file{code-keywords.el} package or wait
till I'll add it to @kdeemacs{}.

@sp 1
@strong{Q.} @emph{I really, really hate identifiersNamedLikeThis. I'd
like to change them to identifiers_named_like_this but the
maintainer of the application/library that I'm hacking on doesn't
agree with me. What can I do? }

@strong{A.} Use the @file{glasses.el} package which changes
identifiersNamedLikeThis to identifiers_named_like_this in the
buffers you're editing and switches them back to their original form
once you save those buffers.

@sp 1
@strong{Q.} @emph{Is it possible to get function completion or
signature display in Emacs? Will it ever be done?}

@strong{A.} Yes and yes. I've been planning on doing this for quite a
while and hopefully will have this finished pretty soon (no dates
though :) ) The first thing that should be done is writing a few
fixes for the Semantic package (@file{c.bnf} to be more exact),
because Semantic doesn't handle templates, member function declared
as const or KDE access specifiers, once this is done all that will be
left is using semanticdb package which efficiently stores and retrieves
large amounts of tokens and then displaying tokens belonging to types at
point which match current context.

@sp 1
@strong{Q.} @emph{Is there a package that would highlight changes that
I made to a certain file?}

@strong{A.} I wouldn't be writing this if there wouldn't - try
@kbd{M-x highlight-changes-mode}.

@sp 1
@strong{Q.} @emph{How to get a diff between the stuff I have in my
local buffer and the file on disk?}

@strong{A.} Use ibuffer package. After @kbd{M-x ibuffer} typing
@kbd{=} over a file will display a diff between the buffer and the
file on the disk.

@sp 1
@strong{Q.} @emph{I want to temporarily highlight certain variable in
a file, how to do it?}

@strong{A.} Type @kbd{M-x hi-lock-mode}, now @kbd{C-x w h
@emph{regexp} @key{RET} @emph{face} @key{RET}} highlights regexp with
face in the current file and @kbd{C-x w r @emph{regexp} @key{RET}}
unhighlights it.
