AutoHotkey: Launch external diff

This script will launch my favorite diff program from within the internal compare window, taking the two files as parameters.

The hotkey is F2, adjust if necessary.

The program is Beyond Compare, adjust if necessary (WinMerge is given as another example, in the commented line).

~F2::
	if WinActive( "ahk_class TFileCompForm" )
	{
		ControlGetText sf_sFile1, TEdit1
		ControlGetText sf_sFile2, TEdit2
		Run "c:\Program Files\Beyond Compare 2\BC2.exe" "%sf_sFile2%" "%sf_sFile1%"
;		Run "c:\Program Files\WinMerge\WinMerge.exe" "%sf_sFile2%" "%sf_sFile1%"
		Return
	}
	Return
