Stolen ALT-F12

Hello,

Some program have stolen my alt-F12, according to some software its "system debugger" whatever that is. I need Alt-F12 for my delphi IDE. Looks hard to change hotkeys in Delphi and even harder to identify and get back a hotkey. Any suggestions?

I have had this before, at the time I looked up what caused this, I don't remember the cause though.
I still have this registry change you can make, it will change the "system debugger hotkey" to the pause key, it helped me back then:

It seems my attached file isn't allowed, see here:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AeDebug]
"UserDebuggerHotKey"=dword:00000013

not that simple to find out.
how:
seems you need to add a keyboard hook to find out which program catches the key
via the hook you can populate an internal list of which key goes to which app

an app:

delphi used to have a tool to show the windows message: winsight. can't find it in the delphi install anymore
alternative:

with that, you can find which app handles the key: (check the info about spy++)
