mintty.ahk

; multiple scrolling modifiers in mintty using AutoHotKey
; save this text as mintty.ahk

; preamble
; --------

; install the latest AutoHotKey from here:
;
;   https://github.com/Lexikos/AutoHotkey_L/releases

; next, configure mintty to scroll when Ctrl is pressed.  then this
; script will allow Shift scrolling as well as Shift+Ctrl scrolling.
; make sure this line is in .minttyrc:
;
;   ScrollMod=ctrl

; the easiest way to start this from within Cygwin and immediately
; return control to bash is probably as follows:
;
;   $ explorer.exe mintty.ahk
;
; attempts to start autohotkey.exe from either bash or cmd /c did
; not return control nicely

; script
; ------

; tell AutoHotKey to reload the script if started again

#SingleInstance force

; tell AutoHotKey not to show a tray icon

#NoTrayIcon

; test whether the mintty window is active

; note: it's possible to find the ahk_class of a window like this:
;
;   WinGetClass, class, A
;   MsgBox, The active window's class is "%class%".
;
; or by using the Window Spy feature from the AutoHotKey tray icon

#IfWinActive ahk_class mintty

; map Shift and Shift+Ctrl hotkeys

; + means Shift
; ^ means Ctrl
; "a::Send b" catches keypress a and sends b instead
; {Key} prevents Key from being interpreted as a string
