; Requires v1.0.41+

; CONFIGURATION SECTION: Customize the script with the following variables.

; The hotkey below is pressed to display the current command's page in the
; help file:
I_HelpHotkey = ^F1

; The string below must exist somewhere in the active window's title for
; IntelliSense to be in effect while you're typing.  Make it blank to have
; IntelliSense operate in all windows.  Make it Pad to have it operate in
; editors such as Metapad, Notepad, and Textpad.  Make it .ahk to have it
; operate only when a .ahk file is open in Notepad, Metapad, etc.
I_Editor = pad

; If you wish to have a different icon for this script to distinguish it from
; other scripts in the tray, provide the filename below (leave blank to have
; no icon). For example: E:\stuff\Pics\icons\GeoIcons\Information.ico
I_Icon = 

; END OF CONFIGURATION SECTION (do not make changes below this point unless
; you want to change the basic functionality of the script).
