Undo action in Photoshop by pressing ctrl?

[Dubs]

To undo an action in Photoshop you have to press Ctrl+Alt+Z. Is there any way to map all three keys to the Ctrl button only?
This is what I've got so far. I need help on the keys.

#IfWinActive ahk_class Photoshop
$Ctrl::
return

I want to tie the above into my existing AutoHotkey script below. I'm confused by what exactly requires a 'return'??

Code: Select all

#IfWinActive ahk_class HoneyviewClassX
$Alt::n
$n::Alt
$Ctrl::b
$b::Ctrl

#IfWinActive ahk_class ATL:ExplorerFrame
$Alt::Ctrl
$Ctrl::Alt

#IfWinActive ahk_class Notepad++
$Alt::Ctrl
$Ctrl::Alt

Try this: (tested)

Code: Select all

#IfWinActive ahk_class Photoshop
~Ctrl::Send, {Blind}!z

A return is required on multiple line hotkeys.

Thank you Xtra, worked perfectly.

though I'd add a #IfWinActive at the end

#IfWinActive ahk_class Notepad++
;your code goes here
#IfWinActive
