Equivalent for xev on windows [closed]

I don't know what your exact requirements are, but AutoHotkey has two features, which enable you to display keyboard and mouse events; however these are focused for the usage in AutoHotkey itself and can be much too rudimentary for your problem:

• To spy on keyboard events you need this minimal script (AutoHotkey.ahk):

  #InstallKeybdHook
  

  Then you can open AutoHotkey -> View -> Key History and script info and display the pressed keys. If you change the focus, this is logged also:

  Window: C:\Users\User\Documents\AutoHotkey.ahk - AutoHotkey v1.1.00.00
  Keybd hook: yes
  (...)
  The oldest are listed first.  VK=Virtual Key, SC=Scan Code, Elapsed=Seconds
  since the previous event.  Types: h=Hook Hotkey, s=Suppressed (blocked),
  i=Ignored because it was generated by an AHK script, a=Artificial,
  #=Disabled via #IfWinActive/Exist, U=Unicode character (SendInput).
  
  VK  SC  Type    Up/Dn   Elapsed Key     Window

• The Mouse spy (AutoHotkey Tray Icon -> Windows Spy) is limited to the coordinates, but detects also the active window:

  

As already posted on ServerFault: my usual quick solution for this is keylook.exe.

Edit: ftp server is no longer working. Source code and exes can be downloaded from http://www.charlespetzold.com/books.html as http://www.charlespetzold.com/src/ProgWin5.zip. Executables are found inChap06 and then KeyView1/Release and KeyView2/Release.
