The Alt+Plus, Alt+Hex method won’t work in Windows or any application if a certain
key in the Registry isn’t set correctly. This could happen if the key was inadvertently
changed or was never switched on. If Alt+Plus, Alt+Hex doesn’t work, take the following
steps:
1. Use the Start menu to run RegEdit.exe.
2. Expand HKEY_Current_User to /Control Panel/Input Method. Find the key (or
create a new string value) called EnableHexNumpad. If you create this string
value, it should have the REG_SZ type.
3. Right-click and modify EnableHexNumpad to give it a value of 1. Close RegEdit.
