1#### Preference Items
2
3 **Preference Items** store several, well, Preferences. Most notable are:
4
5* “smartTypingPairs” – They define pairs of characters so that the second character gets automatically inserted when you type the first character. Try it with `"` (double quote) for example. And try it again while you have some text selected. This saves you time and lets you not forget to insert the closing character of (e.g.) a string.
6* “shellVariables” – This lets you define Shell Variables to be available for Commands in certain contexts. This is e.g. used for the “Comment Line / Selection” Command. (More on that later.)

8As always, the Manual provides [a chapter on Preference Items](http://macromates.com/textmate/manual/preferences_items) for further reading.

17### Special Bundles

19***CAUTION:*** *The “Text” and “Source” Bundles define the basis for most other Bundles. You should not deactivate them!*

21### Conclusion so far
22
23I know this must have been a rough ride until now – but you will thank me at some point for the insight you have gained about the Bundles I think. TextMate is 1000% adaptable and extensible – yes, this number is right. Without those bundles that are mostly written by Users like you and me TextMate would not have 1/10th of its power.
24
25And now for the fun part where we will use all this power.

33Beside the standard navigation keys there are some handy shortcuts (most of which are working throughout Cocoa/OSX applications and are common to people coming from e.g. emacs).
