// Scintilla source code edit control
// @file LexAU3.cxx
// Lexer for AutoIt3 http://www.hiddensoft.com/autoit3
// by Jos van der Zande, jvdzande@yahoo.com
//
// Changes:
// March 28, 2004 - Added the standard Folding code
// April 21, 2004 - Added Preprosessor Table + Syntax Highlighting
// Fixed Number highlighting
// Changed default isoperator to IsAOperator to have a better match to AutoIt3
// Fixed "#comments_start" -> "#comments-start"
// Fixed "#comments_end" -> "#comments-end"
// Fixed Sendkeys in Strings when not terminated with }
// Added support for Sendkey strings that have second parameter e.g. {UP 5} or {a down}
