Hotkey Limitations
Although AutoHook allows you to override all AutoCAD keys and most Windows keys, the following keystrokes cannot be hotkeys:
  • ^!Delete (Ctrl+Alt+Delete)
  • #L (Windows Key + L) — works in XP, but is reserved in Vista and Windows 7/8/10/11
AutoHook also adds the following restrictions due to the use of the {pause} macro command:
  • Unmodified Enter
  • Unmodified Escape
  • ^Enter (Ctrl+Enter)
  • ^!Enter (Ctrl+Alt+Enter)
  • !Enter (Alt+Enter)
  • !Escape (Alt+Escape)
AutoHook further restricts mouse hotkeys to avoid interference with normal AutoCAD function. See Mouse Buttons for more info.
Ignore NumLock State
By default in Windows, holding the Shift key and hitting a NumPad key will send the secondary function of the NumPad key. For example: Shift + NumPad7 will send NumPadHome.
When Ignore NumLock State is On, this functionality is ignored, but when Ignore NumLock State is Off, this feature can cause uninteded outcomes if NumPad keys are used with a Shift Modifier.
Because of this, it is not recommended to use Shift Modifiers when Ignore NumLock State is disabled.
Control (Ctrl) Modifier
If you're experiencing issues with the Ctrl Modifier, set AutoCAD's GRIPMULTIFUNCTIONAL system variable to 2.
