how to change "§" (section symbol) key to write "`" (back quote) I'm using back quote many times but never use the '§' symbol.

I'd like to change the key to always write back quote instead. does anyone know how can I change it programtically?
An easier way with Karabiner is to just add a new Simple Modification (the first tab in Karabiner):

From key: non_us_backslash
To key: grave_accent_and_tilde (`)

Here's a screenshot of that:


Why is that called non_us_backslash and not §?
The &quot;non us backslash&quot; is probably any key directly below the esc key (or the touchbar) (source: this issue).
On the English International, UK English, Dutch, Polish etc. keyboards, that's the key that produces the section symbol §.
