 # Search and Substitute
 This chapter covers two separate but related concepts: search and substitute. Many times, the texts that you are searching for are not straightforward and you must search for a common pattern. By learning how to use meaningful patterns in search and substitute instead of literal strings, you will be able to target any text quickly.
 
-As a side note, in this chapter, I will mainly use `/` when talking about search. Eveything you can do with `/` can also be done with `?`.

-The dot command's power comes from exchanging several keystrokes for one. It is probably not a profitable exchangeto use the dot command for one-keyed-operations like `x`. If your last change requires a complex operation like `cgnconst<esc>`, the dot command reduces nine keypresses into one, a very good trade-off.

 When editing, ask if the action you are about to do is repeatable. For example, if I need to remove the next three words, is it more economical to use `d3w` or to do `dw` then `.` two times? Will you be deleting a word again? If so, then it makes sense to use `dw` and repeat it several times instead of `d3w` because `dw` is more reusable than `d3w`. Keep a "change-driven" mindset while editing.

 Recall from earlier section that macros can be executed using the  command line command `:normal` (ex: `:3,5 normal @a` to execute macro "a" on lines 3-5). If you run `:1,$ normal @a`, you will see that the macro is being executed on all lines except the "foo" line. It works!
 
-Although internally Vim does not actually run the macros in parallel, outwardly, it behaves like such. Vim executes `@a` *independently* on each line from the first line to the last line (`1,$`).
