===== General =====

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

; Win+F12 = Sleep
#F12::DllCall("PowrProf\SetSuspendState", "int", 0, "int", 0, "int", 0)

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

; Alt+Backtick -> Shift+Win_Right (move window to next monitor) -- a shortcut I used on Ultramon for years
!`::Send +#{Right}


</file>

===== Hold down any key =====
<file>
; do right win key + whatever to hold that key down (if it's listed below)
>#w::Send {w down}
>#a::Send {a down}
>#s::Send {s down}
>#d::Send {d down}
>#LButton::Send {LButton down}
>#MButton::Send {MButton down}
>#RButton::Send {RButton down}
>#q::Send {q down}
>#e::Send {e down}
</file>

===== Map gamepad buttons to winamp controls =====
All the function gunk around Joy2 and Joy3 is for keyboard auto-repeat of Win+A and Win+S (which I map to winamp volume control elsewhere).
<file>
; winamp control (if winamp is running)
#If WinExist("ahk_class BaseWindow_RootWnd") ; << this badly named thing refers to winamp
Joy1::Send {Media_Play_Pause}
Joy4::Send {Media_Stop}
Joy6::Send {Media_Next}
Joy8::Send {Media_Prev}

Joy2::
  Send {LWin down}{s down}
  SetTimer, WaitForJoy2, 30  ; 30ms
  return

WaitForJoy2:
  if not GetKeyState("Joy2")  ; The button has been released.
  {
    Send {LWin up}{s up}  ; Release the spacebar.
    SetTimer, WaitForJoy2, off  ; Stop monitoring the button.
    return
  }
  ; Since above didn't "return", the button is still being held down.
  Send {LWin down}{s down}  ; Send another Spacebar keystroke.
  return

Joy3::
  Send {LWin down}{a down}
  SetTimer, WaitForJoy3, 30  ; 30ms
  return

WaitForJoy3:
  if not GetKeyState("Joy3")  ; The button has been released.
  {
    Send {LWin up}{a up}  ; Release the spacebar.
    SetTimer, WaitForJoy3, off  ; Stop monitoring the button.
    return
  }
  ; Since above didn't "return", the button is still being held down.
  Send {LWin down}{a down}  ; Send another Spacebar keystroke.
  return
#If ; EndIf
</file>

===== Make the top edge of the main monitor "sticky" =====
If you have a second monitor //above// the main one, this script will help you still be able to click stuff at the top of the screen without accidentally wandering into the upper monitor.
<file>
SetupClipCheck() ; enable the mouse confinement system (defined below)

; get access to the winapi ClipCursor function, which limits cursor boundaries
ClipCursor( Confine=True, x1=0 , y1=0, x2=1, y2=1 ) 
{
 VarSetCapacity(R,16,0),  NumPut(x1,&R+0),NumPut(y1,&R+4),NumPut(x2,&R+8),NumPut(y2,&R+12)
 Return Confine ? DllCall( "ClipCursor", UInt,&R ) : DllCall( "ClipCursor" )
}

; count the number of loop iterations the mouse has been near the top and un-confine the mouse if there's been enough
SetupClipCheck() {
 SetTimer, ClipCheck, 10
 return
}

top_tick_count := 0   
ClipCheck:
 CoordMode, Mouse, Screen
 MouseGetPos,x,y
 ;ToolTip,%x%:%y%:%top_tick_count%

 If (y < 10) {
   top_tick_count++
 } Else {
   top_tick_count := 0
 }

 if (top_tick_count>15) {
   ClipCursor(False)
 } Else {
   ClipCursor(True, -10000, 0, 10000, 10000)
 }
 return
</file>

===== Extended mouse buttons mapped to media control =====
<file>
XButton2::Media_Play_Pause
XButton1::Media_Next
</file>

===== Mouse click spam =====
Press F7 to toggle auto-clicking over and over as fast as possible.
<file>
i:=0 
F7::SetTimer, Spam, % (i:=!i) ? "10" : "Off" ; uses ternary

Spam: 
   Click
   Send {LButton}
return
</file>

===== Winkey shortcut overrides =====
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 media keys or other key combos that apps can hook without issue.
<file>
; WinAmp+Launchy remaps
#z::Media_Prev
#x::Media_Play_Pause
#c::Media_Play_Pause
#v::Media_Stop
#b::Media_Next
#space::Send ^+{Space}
; ^ Win+Space -> Ctrl+Shift+Space

; old simple winamp remaps -- the newer ones above let it work for non-winamps, such as spotify
;#x::#^x
;#b::#^b
</file>
===== Auto mouse =====
<file>
; 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
return
#i::
SetTimer DoClick,off
SoundBeep 660,100
SoundBeep 440,100
return
DoClick:
  Send {LButton}
  SoundBeep 200,10
return

</file>

===== FoxIt =====
The F5 for reload only works if the active file is the most recently opened.

<file>
; FoxIt keys: F5=reload
#IfWinActive, ahk_class classFoxitReader
F5::Send ^w!fr1
#IfWinActive
</file>

===== Terraria =====
<file>
; 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
</file>


===== Suppress F1 in Explorer, Word, and Excel =====
The code below will replace the annoying help popup with a low-pitched beep.  Change "SoundBeep..." to "Return" for silent operation.
<file>
; Suppress F1 in Explorer/Word/Excel -- replace the annoying help popup with a low-pitched beep
#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
</file>
===== Minecraft movement =====

<file>
; Ctrl+W = hold W (auto-run)
; Ctrl+LButton = hold LButton (auto-mine)
; Ctrl+RButton = hold RButton (auto-use)
; MButton = Sprint without double-tapping W
; Ctrl+MButton = hold MButton (auto-sprint)

#IfWinActive Minecraft ahk_class SunAwtFrame
^w::
 Send {w down}
 SoundBeep 500,100
 return

^LButton::
 Send {LButton down}
 SoundBeep 500,100
 return

^RButton::
 Send {RButton down}
 SoundBeep 500,100
 return

MButton:: 
 SetKeyDelay 55
 Send {w down}{w up}{w down}
 KeyWait MButton
 Send {w up}
 return

^MButton:: 
 SetKeyDelay 55
 Send {w down}{w up}{w down}
 SoundBeep 500,100
 return
#IfWinActive
