How do I change my Tilde key to produce the n-dash when pressed?

Question

How can I change a key on my keyboard so that it produces a different character than what it was designed to produce? I find the Tilde key (the little key with ∼ above the Tab key) useless and I would like it to produce the n-dash (–) when I press it. I am not a programmer, so I would like a very dumbed-down explanation with steps. Thanks to anyone who makes their time to respond to this.
My operating system is Windows 10 and the language of the keyboard is Slovene.

Answer 1

You can remap a key

• using an AutoHotkey script (see Remapping Keys) or
• via the Windows registry using a program like KeyTweak or SharpKeys.

For the advantages and disadvantages of each approach, see registry remapping.

EDIT:

Remapping per AutoHotkey:

~::–

EDIT 2:

In the rare case where a key has no name or the standard code doesn't work, hotkeys can be triggered by using the 3-digit hexadecimal scan code (SC) of a key.

The scan code of a key can be determined by following the steps at Special Keys:

• Run a script with keyboard hook
• open the AutoHotkey window (context menu in systray, Open item)
• go to View > Key History and script info
• type the key
• hit F5 to see the code

Then you can try e.g.

SC174::SendInput –

Replace 174 by the number found in the Key History.
