== Tips & Tricks ==
In order to insert some special template like MathBoxes, vectors shapes, angles etc., you have to put these in the '''setExpression''' argument :
*\\1angle : The text rendered inside is will be displayed under the "angle" shape
*\\1circle : Symbol for circle
*\\1keyword :
*\\1line : Symbol for line (parenthesis)
*\\1lineseg : Symbol for line segment
*\\1ray :
*\\1rtri :
*\\1subhead :
*\\1subscrp : Subscript text
*\\1supersc : Superscript text
*\\1title :
*\\1tri : Triangle symbol
*\\1vector : The text rendered inside is will be displayed under the vector arrow.
*\\1word :
*\\0el {''content''} : Inserts a MathBox with the ''content'' inside it.
For example, '''editor:setExpression("\\1vector AB")''' will render as : http://i.imgur.com/aqVd8.jpg
