1. Your Latex
   1. Editing Cycle
      1. A text editor is used to create a source file
      2. “Typesets” the source file and views the result on the monitor
      3. Making changes and observing the results of these changes
      4. Print the file and mostly creates a PDF file of the typeset version
   2. Three productivity tools
      1. Synchronization
         1. move quickly between the source file and the typeset file
      2. Block comment
         1. comment or uncomment a block of text at one time
      3. Jump to a line
         1. jump to a line specified in the source file by the line number
2. Typing text
   1. A source file
      1. text
      2. math (formulas)
      3. instructions (commands) to LaTeX
         1. command with an argument
         2. command without an argument
         3. environment.
            1. content: the text that is typed between two environment commands
      4. start with a backslash ( \ )
   2. The keyboard
      1. used to type text
         1. a-z A-Z 0-9 + = * / ( ) [ ]
      2. punctuation marks can be used
         1. , ; . ? ! : ` ' -
         2. the space bar, the Tab key, and the Return (or Enter) key
      3. special keys used in LaTeX commands
         1. # $ % & ~ _ ^ \ { } @ " |
            1. Only @ requires no special command
            2. Others need to insert a backslash ( \ ) before
   3. Your first note
      1. comments
         1. everything on the line after % is ignored
      2. document class
         1. control how the document is formatted
      3. environment
         1. \begin{document} and \end{document}
      4. text
         1. typed within the document environment
   4. Lines too wide
      1. LaTeX uses points (pt) to measure distances
      2. hyphenate a hyphenated word only at the hyphen
      3. LaTeX’s standard hyphenation routine cannot handle German hyphenation and so on
   5. More text features
      1. display the date on which the document is typeset
         1. \today
      2. environments to justify text
         1. \begin{flushright} ... \end{flushright}
         2. \begin{center} ... \end{center}
         3. \begin{flushleft} ... \end{flushleft}

            1. bold text
         3. \texttt
            1. typewriter style text
      4. form of the LaTeX commands
         1. backslash( \ )
         2. command name
            1. terminated by the first nonalphabetic character
            2. case sensitive
         3. arguments (if have)
            1. takes the next character as argument if braces non-exist
      5. multiple role of hyphens
         1. Double hyphens are used for number ranges
            1. 89--64 as 89-64
         2. triple hyphens for the em dash punctuation mark
            1. --- as —
      6. new line command
         1. \\ (or \newline):
         2. create additional space between lines
            1. \\[distance]
