GoToTilla v0.21 by budRich
http://www.autohotkey.com/board/topic/95536-gototilla-a-combination-of-goto-and-tillagoto/
A combination of: GoTo by Avi Aryan
http://www.autohotkey.com/board/topic/95009-goto-hotkeys-hotstrings-functions-and-labels-in-any-editor/
and TillaGoto by TheGood
http://www.autohotkey.com/forum/viewtopic.php?t=41575
TheGood was inspired by Rajats Active GoTo
http://www.autohotkey.com/board/topic/10936-active-goto-v4/
#####################
 
Go To functions, labels, hotkeys and hotstrings in any editor.
The only requirement is that the Editor shows file full path in Title Bar and has a Goto (Ctrl+G) option.
Examples of such editors - Notepad++, Sublime Text, PSPad, ConTEXT
 
Ctrl+Space to show a list of all functions,hotkeys,hotstrings and labels.
Type to narrow list down, navigate with mouse or arrowkeys, select with doubleclick or Enter.
