Why do hotkeys such as

always use the keyboard hook?

I use AutoHotkey_L v1.0.96.00 and Windows 7 64bit.

My guess is that sleep requires and/or uses the keyboard hook, but I don't know.

As far as I know, any hotKey that cannot be created with RegisterHotkey needs Keyboard hook.

So, hotkeys involving Up, Down, Right, Left, PgUp, PgDown etc. cannot be created with RegisteredHotkey?

As far as I understand this is due to IsDualStateNumpadKey keys, so any key that exist additionally on Numpad uses k-hook. So even Up::MsgBox will use k-hook.

But why does F12 need the k-hook?

Thanks HotKeyIt.

I was in another thread some months ago and we "discovered" that hotkey F12 "triggered" the use of k-hook.
But nobody had an answer why.

I'm just curious ... why do you care?

I use a mouse which has some extra buttons. I use one of them for "go forward", which usually is Alt+Right. However one of my programs doesn't obey the Alt+Right convention. So I implemented a contextual Alt+Right hotkey for this program, which should be triggered by the Alt+Right sent by the mouse button. However it didn't work, since Alt+Right uses the keyboard hook and thus cannot be triggered by the send command. (This is one of the rare cases where the keyboard hook is a disadvantage.)
Meanwhile, I worked around by using an intermediary "helper hotkey".
