Below are some useful recipes. See also: Using AutoHotKey to map keys on the Amtelco KB163 Unified Keyboard.

; General controls:
;   Win+Esc       to reload
;   Win+Shift+Esc to exit
;   Win+Ctrl+Esc  to exit
#Escape::Reload
#+Escape::ExitApp
#^Escape::Edit

; Win+Backtick = Sleep
#`::DllCall("PowrProf\SetSuspendState", "int", 0, "int", 0, "int", 0)

; Win+M = toggle mute
#m::Send {Volume_Mute}

Windows by default binds Win+X, Win+B, and Win+Space to stuff I don't care about. The script below will remap these to some random key combos that you can then hook with WinAmp, Launchy, etc.

; WinAmp+Launchy remaps
#x::[
#b::]
#space::SendInput ![

; Auto mouse click: 
;  Win+Shift+I      to auto click slowly
;  Win+Shift+Ctrl+I to auto click quickly
;  Win+I            to auto stop
#+i::
SetTimer DoClick,500
SoundBeep 440,100
SoundBeep 660,100
return
#+^i::
SetTimer DoClick,50
SoundBeep 440,100
SoundBeep 660,100
SoundBeep 880,100

#i::
SetTimer DoClick,off
SoundBeep 660,100
SoundBeep 440,100

DoClick:
  Send {LButton}
  SoundBeep 200,10

The F5 for reload only works if the active file is the most recently opened. The F6 will switch to a MinTTY session and issue a "make again" command. Obviously this latter one is very specific.

; FoxIt keys: F5=reload and F6=latex build
#IfWinActive, ahk_class classFoxitReader
F5::Send ^w!f1
F6::
WinActivate ahk_class mintty
Send make again{enter}
WinActivate ahk_class classFoxitReader
return
#IfWinActive

; Terraria: middle click is turbo left click
#IfWinActive, ahk_class WindowsForms10.Window.8.app.0.ea7f4a_r16_ad1
MButton::
SetTimer DoClick,50
SoundBeep 880,50
return
MButton up::
SetTimer DoClick,off
SoundBeep 440,50
return
#IfWinActive

The code below will replace the annoying help popup with a low-pitched beep. Change "SoundBeep…" to "Return" for silent operation.

#IfWinActive ahk_class CabinetWClass
F1::SoundBeep 110,100
#IfWinActive ahk_class OpusApp
F1::SoundBeep 110,100
#IfWinActive ahk_class XLMAIN
F1::SoundBeep 110,100
#IfWinActive

; Ctrl+W = hold W (auto-run)
; Ctrl+LButton = hold LButton (auto-mine)
