AutoItSetOption ( "ExpandVarStrings" [, param ] ) Changes how literal strings and variable/macro ($ and @) symbols are interpreted.  By default strings are treated literally, this option allows you to use variables and macros inside strings, e.g., "The value of var1 is $var1$". 1 = expand variables (when in this mode and you want to use a literal $ or @ then double it up: "This is a single dollar $$ sign". 0 = do not expand variables (default)

A -1 for left or top parameter don't increment the start. So next line is -1,offset; next cell is offset,-1; current cell is -1,-1. Obviously "offset" cannot be -1 which reserved to indicate the no increment. But if you can use a multiple of the width you choose to skip or go back. 
AutoItSetOption ( "GUIDataSeparatorChar" [, param ] ) Define the character which delimits subitems in GUICtrlSetData. The default character is '|'. 
AutoItSetOption ( "GUIOnEventMode" [, param ] ) Enable/disable OnEvent functions notifications. 0 = (default) disable. 1 = enable.

AutoItSetOption ( "MustDeclareVars" [, param ] ) If this option is used then all variables must be pre-declared with Dim, Local or Global before they can be used - removes the chance for misspelled variables causing bugs. 1 = Variables must be pre-declared 0 = Variables don't need to be pre-declared (default) 
AutoItSetOption ( "PixelCoordMode" [, param ] ) Sets the way coords are used in the pixel functions, either absolute coords or coords relative to the window defined by hwnd (default active window): 0 = relative coords to the defined window 1 = absolute screen coordinates (default) 2 = relative coords to the client area of the defined window 
AutoItSetOption ( "SendAttachMode" [, param ] ) Specifies if AutoIt attaches input threads when using Send() function.  When not attaching (default mode=0) detecting the state of capslock/scrolllock and numlock can be unreliable under NT4.  However, when you specify attach mode=1 the Send("{... down/up}") syntax will not work and there may be problems with sending keys to "hung" windows.  ControlSend() ALWAYS attaches and is not affected by this mode. 0 = don't attach (default) 1 = attach 
AutoItSetOption ( "SendCapslockMode" [, param ] ) Specifies if AutoIt should store the state of capslock before a Send function and restore it afterwards. 0 = don't store/restore 1 = store and restore (default) 
AutoItSetOption ( "SendKeyDelay" [, param ] ) Alters the the length of the brief pause in between sent keystrokes.  A value of 0 removes the delay completely. Time in milliseconds to pause (default=5). 
AutoItSetOption ( "SendKeyDownDelay" [, param ] ) Alters the length of time a key is held down before being released during a keystroke.  For applications that take a while to register keypresses (and many games) you may need to raise this value from the default.  A value of 0 removes the delay completely. Time in milliseconds to pause (default=5). 
AutoItSetOption ( "TCPTimeout" [, param ] ) Defines the time before TCP functions stop if no communication. Time in milliseconds before timeout (default=100).

AutoItSetOption ( "TrayIconDebug" [, param ] ) If enabled shows the current script line in the tray icon tip to help debugging. 0 = no debug information (default) 1 = show debug 
AutoItSetOption ( "TrayIconHide" [, param ] ) Hides the AutoIt tray icon.  Note:  The icon will still initially appear ~750 milliseconds. 0 = show icon (default) 1 = hide icon 
AutoItSetOption ( "TrayMenuMode" [, param ] ) Extend the behaviour of the script tray icon/menu. This can be done with a combination (adding) of the following values. 0 = default menu items (Script Paused/Exit) are appended to the usercreated menu; usercreated checked items will automatically unchecked; if you double click the tray icon then the controlid is returned which has the "Default"-style (default). 1 = no default menu 2 = user created checked items will not automatically unchecked if you click it 4 = don't return the menuitemID which has the "default"-style in the main contextmenu if you double click the tray icon 8 = turn off auto check of radio item groups

AutoItSetOption ( "WinTextMatchMode" [, param ] ) Alters the method that is used to match window text during search operations. 1 = Complete / Slow mode (default) 2 = Quick mode In quick mode AutoIt can usually only "see" dialog text, button text and the captions of some controls.  In the default mode much more text can be seen (for instance the contents of the Notepad window). If you are having performance problems when performing many window searches then changing to the "quick" mode may help. 
AutoItSetOption ( "WinTitleMatchMode" [, param ] ) Alters the method that is used to match window titles during search operations. 1 = Match the title from the start (default) 2 = Match any substring in the title 3 = Exact title match 4 = Advanced mode, see <a href="../intro/windowsadvanced.htm">Window Titles & Text (Advanced)</a> -1 to -4 = force lower case match according to other type of match.
