Slash commands in Mattermost and Slack allow you to control GitLab and view GitLab content right inside your chat client, without having to leave it. For Slack, this requires a [project service configuration](../user/project/integrations/slack_slash_commands.md). Simply type the command as a message in your chat client to activate it.
Commands are scoped to a project, with a trigger term that is specified during configuration.
We suggest you use the project name as the trigger term for simplicity and clarity.
Taking the trigger term as `project-name`, the commands are:
| Command | Effect |
| ------- | ------ |
| `/project-name help` | Shows all available slash commands |
| `/project-name issue new <title> <shift+return> <description>` | Creates a new issue with title `<title>` and description `<description>` |
| `/project-name issue show <id>` | Shows the issue with id `<id>` |
| `/project-name issue search <query>` | Shows up to 5 issues matching `<query>` |
| `/project-name deploy <from> to <to>` | Deploy from the `<from>` environment to the `<to>` environment |
Note that if you are using the [GitLab Slack application](https://docs.gitlab.com/ee/user/project/integrations/gitlab_slack_application.html) for
your GitLab.com projects, you need to [add the `gitlab` keyword at the beginning of the command](https://docs.gitlab.com/ee/user/project/integrations/gitlab_slack_application.html#usage).
