+# { title }
+
+## File list
+
+Once you have [opened](./menu/file) files, they will be shown as tabs in the file list located at the bottom of the map.
+You can reorder the files by dragging and dropping the tabs.
+When many files are open, you can scroll through the list of tabs to navigate between them.
+
+### File selection
+
+By clicking on a tab, you can switch between the files to inspect their statistics, and apply [edit actions](./menu/edit) and [tools](./toolbar/) to them.
+By holding the <kbd>Ctrl/Cmd</kbd> key, you add files to the selection, and by holding <kbd>Shift</kbd>, you can select a range of files.
+Most of the [edit actions](./menu/edit) and [tools](./toolbar/) can be applied to multiple files at once.
+
+<DocsNote>
+    You can also navigate through the files using the arrow keys on your keyboard, and use <kbd>Shift</kbd> to add files to the selection.
+</DocsNote>
+
+### Edit actions
+
+By right-clicking on a file tab, you can access the same actions as in the [edit menu](./menu/edit).
+
+### Vertical layout
+
+As mentioned in the [view options section](./menu/view), you can switch between a horizontal and a vertical layout for the file list.
+The vertical file list is useful when you have many files open, or files with multiple [tracks, segments or waypoints](../gpx).
+Indeed, this layout allows to inspect the content of the files through collapsible sections.
+
+You can apply [edit actions](./menu/edit) and [tools](./toolbar/) to inner file items.
+Furthermore, you can drag and drop the inner items to reorder them, or move them in the hierarchy or even to another file.
+
+## Elevation profile and statistics
+
+At the bottom of the interface, you can find the elevation profile and statistics for the current selection.
+
+### Interactive statistics
+
+When hovering over the elevation profile, a tooltip will show statistics at the cursor position.
+To get the statistics for a specific section of the elevation profile, you can drag a selection rectangle on the profile.
+Click on the profile to reset the selection.
+
+### Additional data
+
+Using the buttons on the right of the elevation profile, you can optionally color the elevation profile by:
+- **Slope** <TriangleRight size="16" class="inline-block" style="margin-bottom: 2px" /> information computed from the elevation data
+- **Surface** <BrickWall size="16" class="inline-block" style="margin-bottom: 2px" /> data coming from <a href="https://www.openstreetmap.org/" target="_blank">OpenStreetMap</a>'s <a href="https://wiki.openstreetmap.org/wiki/Key:surface" target="_blank">surface</a> tags. This is only available for files created with **gpx.studio**.
+
+If your selection includes it, you can also visualize: **Speed** <Zap size="16" class="inline-block" style="margin-bottom: 2px" />, **Heart rate** <HeartPulse size="16" class="inline-block" style="margin-bottom: 2px" />, **Cadence** <Orbit size="16" class="inline-block" style="margin-bottom: 2px" />, **Temperature** <Thermometer size="16" class="inline-block" style="margin-bottom: 2px" /> and **Power** <SquareActivity size="16" class="inline-block" style="margin-bottom: 2px" /> data on the elevation profile.

+
+Welcome to the official guide of **gpx.studio**!
+It will walk you through all the components and tools of the interface, and help you become a proficient user of the application.
+
+<DocsImage src={interfaceScreenshot} alt="Screenshot of the gpx.studio interface" />
+
+As you can see on the screenshot above, the interface is divided into four main sections organized around the map.
+Before we dive into the details of each section, let's have a quick overview of the interface.
+
+## Menu
+
+At the top of the interface, you will find the [main menu](./menu).
+This is where you can access common actions such as opening, closing and exporting files, undoing and redoing actions, and adjusting the settings of the application.
+
+## Files and statistics
+
+At the bottom of the interface, you will find the list of files that are currently open in the application.
+You can click on a file to select it, and display its statistics below the list.
+As we will see in the [dedicated section](./files-and-stats), you can select multiple files at once, and also switch to a vertical layout of the list for advanced file management.
+
+## Toolbar
+
+On the left side of the interface, you will find the [toolbar](./toolbar), which contains all the tools you can use to edit your files.
+
+## Map controls
+
+Finally, on the right side of the interface, you will find the [map controls](./map-controls).
+These allow you to navigate the map, zoom in and out, and switch between different map styles.

+Unlike the file actions, the edit actions can potentially modify the content of the currently selected files.
+Moreover, when the vertical layout of the files list is enabled (see [Files and statistics](../files-and-stats)), they can also be applied to [tracks, segments and points of interest](../gpx).
+Therefore, we will refer to *file items* to designate the elements that can be modified by these actions.
+Note that except for the undo and redo actions, the edit actions are also accessible through the context menu (right-click) of the file items.
+
+### <Undo2 size="16" class="inline-block" style="margin-bottom: 2px" /><Redo2 size="16" class="inline-block" style="margin-bottom: 2px" /> Undo and redo
+
+Using these buttons, you can undo or redo the last actions you performed.
+This applies to all actions of the interface but not to view options, application settings or map navigation.
+
+### <Info size="16" class="inline-block" style="margin-bottom: 2px" /> Info...

+
+### <EyeOff size="16" class="inline-block" style="margin-bottom: 2px" /> Hide/unhide
+
+Toggle the visibility of the selected file items on the map.
+
+### <FileStack size="16" class="inline-block" style="margin-bottom: 2px" /> Select all
+
+Add all file items in the current hierarchy level to the selection.
+
+### <ClipboardCopy size="16" class="inline-block" style="margin-bottom: 2px" /> Copy
+
+Copy the selected file items to the clipboard.
+

+
+# { title }
+
+This menu provides options to rearrange the interface and the map view.
+
+### <MountainSnow size="16" class="inline-block" style="margin-bottom: 2px" /> Elevation profile
+
+Hide the elevation profile to make room for the map, or show it to inspect the current selection.
+
+### <GalleryVertical size="16" class="inline-block" style="margin-bottom: 2px" /> Vertical file list
+
+Switch between a vertical and a horizontal layout for the file list.
+The [vertical file list](../files-and-stats) is useful when you have many files open, or files with multiple [tracks, segments or waypoints](../gpx).
+
+### <Map size="16" class="inline-block" style="margin-bottom: 2px" /> Switch to previous basemap
+
+Change the basemap to the one previously selected through the [map layer control](../map-controls).
+
+### <Layers2 size="16" class="inline-block" style="margin-bottom: 2px" /> Toggle overlays
+
+Toggle the visibility of the map overlays selected through the [map layer control](../map-controls).
+
+### <Coins size="16" class="inline-block" style="margin-bottom: 2px" /> Distance markers
+
+Toggle the visibility of distance markers on the map.
+They are displayed for the current selection, like the [elevation profile](../files-and-stats).
+
+### <Milestone size="16" class="inline-block" style="margin-bottom: 2px" /> Direction arrows
+
+Toggle the visibility of direction arrows on the map.
+
+### <Box size="16" class="inline-block" style="margin-bottom: 2px" /> Toggle 3D
+
+Enter or exit the 3D map view.
