====== OpenOffice.org tips/cheat sheet ======

Stuff I often need and often forget, mainly related to the formula-editor

===== Numbered equations =====

  * Enter ''fn'' followed by F3 on an empty paragraph to create a numbered equation (2x1 table, formula on left, auto number of right)
  * Alternatively, use a 2x1 table and do it manually

===== Formula editor =====

==== Greek letters ====

Precede the **localised** name with ''%'', i.e.:

α φ υ => OOo in English: <code>%alpha %phi %upsilon</code>
\\
α φ υ => OOo in Spanish: <code>%alfa %fi %ípsilon</code>\\
   Quirk: in Spanish "mu" (μ) must be written as ''%my'' (despite being an archaic/rare form)

=== Uppercase ===

Write the **full** name in uppercase

Α Φ Υ => OOo in English: <code>%ALPHA %PHI %UPSILON</code>
\\
Α Φ Υ => OOo in Spanish: <code>%ALFA %FI %ÍPSILON</code>

==== Questioned equal to symbol (≟ / "=?") ====

  * Option 0: (best looking, see [[Text:Common_Unicode|unicode stuff]]) <code>x "≟" y</code> i.e. →[ «''x "''», «CTRL+Shift+U, 225f», «''" y''» ]←

Previously: (Source: http://www.oooforum.org/forum/viewtopic.phtml?t=90309)

  * Option 1: In-editor typesetting: <code>x "=" csup "?" y</code>
    * Con: «''?''» is placed too high
  * Option 2: [[http://ooolatex.sourceforge.net/|OOoLatex]]: <code>x \stackrel{?}{=} y</code> or ((Second alternative didn't work for me)) <code>x \overset{?}{=} y</code>
    * Con: Not editable, Worse font antialiasing/hinting

==== Vertical line ( {x | x > 3} ) ====

<code>mline</code>

==== Limits ====

<code>lim csub {x toward infinity}</code>

==== System of equations ====

<code>
alignr left none
    stack {
        {Equation1} #
        {Equation2} #
        {Equation3}
    } right rbrace
</code>

Where ''alignr'' aligns the equations to the right, ''left none'' allows an unbalanced bracket and ''right rbrace'' adds a right angled bracket.

==== Formula text size ====

See: http://wiki.services.openoffice.org/wiki/Documentation/FAQ/Formula/How_do_I_change_the_size_of_a_subformula%3F

Quick recap: (copy-pasted from the above link)
There are five variants of the size-changing command:\\
   * size 20 a typesets a with the font size 20 pt.
   * size +5 a typesets a with current font size plus 5pt.
   * size -5 a typesets a with current font size minus 5pt.
   * size *1.5 a typesets a with current font size multiplied by 1.5.
   * size /1.5 a typesets a with current font size divided by 1.5.


==== Literal text ====

To write text that dowsn't display as a variable (in italics) use either "func" or double quotes (typographic double quotes are not recognised)

   func Hello func World
or

   "Hello World"


===== Text editor =====

Most symbols are included in Unicode so they can be inserted through unicode codes in GNOME (CTRL+Shift+U, Unicode code point).
