In `*ielm*`:

```
ELISP> `(emacs-version \, emacs-version)
(emacs-version . "28.2")
```

________________

In `custom-file`:

```
(custom-set-variables
 '(var `(a . ,b)))
```

Then change some options by GUI menu, and click `Save Options`:

```
(custom-set-variables
 '(var `(a \, b))
 '(changed-option new-value))
```
