# Properties
Vim Vixen can be configured by defining settings in a JSON document, e.g.:
```json
{
"properties": {
"smoothscroll": true,
"hintchars": "abcdefghijklmnopqrstuvwxyz",
"complete": "sbh"
}
}
```
If a property is not set, it will be used the default.
Properties can be temporarily overridden by using the `:set` command in the
console.
The following properties are available:
## `smoothscroll`
Enable/disable smooth scrolling.
```
:set smoothscroll " enable smooth scrolling
:set nosmoothscroll " disable smooth scrolling
```
## `hintchars`
Set hint characters. They will be used to follow links in the page.
```
:set hintchars=0123456789
```
## `complete`
Set completion items on `open`, `tabopen`, and `winopen` commands.
The allowed value is character sequence of `s`, `b`, or `h`.
Hit Tab or Shift+Tab to select an item from the completion list.
Each character represents the following:
- `s`: search engines
- `b`: bookmark items
- `h`: history items.
```
:set complete=sbh
```
