Disable all 'Ctrl' key shortcuts in AutoHotkey?

Question

I'm trying to lock down a kiosk PC and need to disable various 'Ctrl + key' keyboard shortcuts.
I started by disabling them individually using AutoHotkey...

^F4::return
^w::return
^+w::return
^Esc::return
^+Esc::return
;etc...

but keep discovering new ones shortcuts (did you know that 'Ctrl + Q' in IE8 displays a tab thumbnail page). So I tried to disable the Ctrl key completely using stuff like:

LCtrl::return
RCtrl::return
~Ctrl::return
^::return

with no luck.

Any ideas?

Answer 1

For the standard shortcuts, refer to this list and setup a hotkey instance to override it. For example, I made an ALT & F4 hotkey, which would normally close the active window, and made it enter some text instead. It works:

ALT & F4::
Send foobar ; This line sends keystrokes to the active (foremost) window.
return

That only fixes each instance. To disable a key (ALT) by itself use:

ALT::Return

For more on that see this.

Watch out for other key combinations made possible by installed software/reg edits such as this video card instance.

You might take a look at Opera Kiosk mode.

Answer 3

The easiest way to solve this would be simply to remap the control key to the shift key. That way, control+v becomes shift+v, which is rather less dangerous. It works on my computer.

Control::Shift
