-After emacs has started, type ''alt-x setnumpad'' to activate the normal numberpad. If you want to deactivate it, type ''alt-x setnumpad''. Note: This is not very sophisticated, as just the configuration file is loaded again.

+==== Adding goto-line ====
+A useful little command when coding with emacs is **goto-line**. To assign it a shortcut, add in your ''~/.emacs'':
+<code>
+;; == goto line ==
+(define-key global-map "\C-xg" 'goto-line)
+</code>
+Goto-line then is executed with ''ctrl-x g''.
+==== Changing the font permanently ====
+To permanently change the font in emacs, do the following:
+  * Type ''xfontsel'' in a terminal. A window will appear. Choose your desired font by selecting ''fndry'', ''fmly'', etc. You will end up with a string that exactely describes your font.
+  * Start emacs and go to the *scratch* buffer. Type: ''prin1-to-string (x-list-fonts "font-you-whant-to-check or pattern"))'' where you put in the selected font from xfontsel. Place the cursor after the last closing parenthesis and type CTRL-j. A list of available fonts with the given pattern will appear.
+  * Open your .emacs file and add the following line:
+<code>
+(set-default-font "the font you want to choose")
+</code>
+for example
+<code>
+(set-default-font "-adobe-courier-medium-r-normal--12-120-75-75-m-70-iso8859-10")
+</code>
+  * Close emacs and restart it. Your default font should now be set to the font you chose.
