Two simple and useful AHK scripts

[barbudo2005]

This are two simple and useful scripts in AHK I found somewhere:

VOLUME KEYS

; Volume up
; SHIFT + "+"  Numpad

+NumpadAdd::    
Send {Volume_Up} ;shift + numpad plus
;Send ^!{Up}
return

; Volume down
; SHIFT + "-" Numpad

+NumpadSub:: 
Send {Volume_Down} ;shift + numpad minus
;Send ^!{Down}
return

;Mute
;Break key

break::
Send {Volume_Mute} ; PAUSE key mutes
;Send ^!{Home}
return

CONVERT A TEXT TO UPPER, LOWER OR CAPTITALIZED

#NoEnv  ; Recommended for performance and compatibility with future AutoHotkey releases.
SendMode Input  ; Recommended for new scripts due to its superior speed and reliability.
SetWorkingDir %A_ScriptDir%  ; Ensures a consistent starting directory.

; CONVERT TEXT TO UPPER
; CTRL + "u"

^u::                         
 OldClipboard:= Clipboard
 Clipboard:= ""
 Send, ^c ;copies selected text
 ClipWait
 StringUpper Clipboard, Clipboard
 Send %Clipboard%
 Sleep 1000
 Clipboard:= OldClipboard
return

; CONVERT TEXT TO LOWER
; CTRL + "l"

^l::                          
 OldClipboard:= Clipboard
 Clipboard:= ""
 Send, ^c ;copies selected text
 ClipWait
 StringLower Clipboard, Clipboard
 Send %Clipboard%
 Sleep 1000
 Clipboard:= OldClipboard
return

; CONVERT TEXT TO CAPITALIZED
; CTRL + "z"

^z::                          
 OldClipboard:= Clipboard
 Clipboard:= ""
 Send, ^c ;copies selected text
 ClipWait
 StringUpper Clipboard, Clipboard, T
