+# File finder
+
+_**Note:** This feature was [introduced][gh-9889] in GitLab 8.4._
+
+---
+
+The file finder feature allows you to quickly shortcut your way when you are
+searching for a file in a repository using the GitLab UI.
+
+You can find the **Find File** button when in the **Files** section of a
+project.

+
+---
+
+For those who prefer to keep their fingers on the keyboard, there is a
+[shortcut button](shortcuts.md) as well, which you can invoke from _anywhere_
+in a project.
+
+Press `t` to launch the File search function when in **Issues**,
+**Merge requests**, **Milestones**, even the project's settings.
+
+Start typing what you are searching for and watch the magic happen. With the
+up/down arrows, you go up and down the results, with `Esc` you close the search
+and go back to **Files**.
+
+## How it works
+
+The File finder feature is powered by the [Fuzzy filter] library.
+
+It implements a fuzzy search with highlight, and tries to provide intuitive
+results by recognizing patterns that people use while searching.
+
+For example, consider the [GitLab CE repository][ce] and that we want to open
+the `app/controllers/admin/deploy_keys_controller.rb` file.
+
+Using fuzzy search, we start by typing letters that get us closer to the file.
+
+**Protip:** To narrow down your search, include `/` in your search terms.
