# Blacklist
## Blacklist
The blacklist allows you to disable the plugin for certain pages by URL patterns.
For instance, `"*.slack.com"` blocks the add-on on any Slack channels.
It also allows you to disable on localhost by `localhost:8000` (port is necessary).
You can also specify path patterns to disable sites on the URL matched with the patterns.
```json
{
"blacklist": [
"*.slack.com",
"localhost:8000",
"example.com/mail/*"
]
}
```
You can toggle Vim Vixen between disabled and enabled with shift+Esc.
## Partial Blacklist
The partial blacklist disables certain keys for each webpage separately.
This is enabled by describing object with `"url"` and `"keys"` instead of a string in the blacklist.
To disable j and k keys (scroll down and up) on github.com as an example, describe target url and disabled keys as the following:
```json
{
"blacklist" [
{ "url": "github.com", "keys": ["j", "k"] }
]
}
```
The partial blacklist blocks all operations starting with the keys but not exactly-matched.
That means if the g described in "keys" field, it block all operation starting with g, such as gg, gt, and gT.
