# Reuse label selections with Quick filters

*Quick filters* capture label and value selections from supported pages as you
investigate, so you can apply them again as
[list variable](/observe/dashboards/customization/dashboard-variables#configure-a-list-variable)
values on a dashboard. Text and interval variables aren't updated from quick filters.

## Where Quick filters capture entries

Observability Platform adds a Quick filters entry when variable or signal data is
available on the page, including when you open or change selections on:

* An [alert details](/investigate/alerts/alert-details) page, from the alert's
  firing signals
* A [monitor](/investigate/alerts/monitors) details page, after signal options load
  and you choose a signal combination
* An [SLO](/observe/slo) details page that includes signal selection
* A dashboard that has
  [list variables](/observe/dashboards/customization/dashboard-variables#configure-a-list-variable),
  when variable values are set
* A [Services](/observe/services) page, from the pinned scopes at the top of the page
* A [Logs Explorer](/investigate/querying/query-logs) page, from the fields and values
  in your log query
* A [Metrics Explorer](/investigate/querying/metrics/explorer) page, from equality (`=`)
  label matchers in a single enabled PromQL query when the explorer has no formulas

Each entry lists the resource name, captured values, and time. Observability Platform
keeps all [favorite](/navigate/favorites) entries and a limited number of your most
recent entries that aren't favorites.

## Use Quick filters on a dashboard

Quick filters apply only to list variables on the dashboard you're viewing.

1. Open the dashboard. [View a list of all dashboards](/observe/dashboards#view-dashboards)
   or select from a [list of dashboards in a collection](/administer/collections/home).
2. In the dashboard variables bar, click the **Quick filters** dropdown.

   The dropdown has three tabs:

   * **Saved**: Your [saved views](/observe/dashboards/customization/dashboard-variables#manage-saved-views).
   * **My recents**: Entries in reverse chronological order.
   * **My favorites**: Entries you marked as a **<Icon icon="star" /> favorite**.

### Apply recent filters in one click

When a recent entry matches list variables on this dashboard and those values aren't
already applied, a history icon button labeled **Apply recent filters** appears next to
the **Quick filters** dropdown. Hold the pointer over the button to preview the entry,
then click to apply it without opening the dropdown.

Observability Platform picks the most recent applicable entry from the **My recents** tab.
The button is disabled when nothing matches this dashboard; hold the pointer over a
disabled button for guidance. After you apply from the button, it stays hidden for the
rest of the visit to this dashboard.

### Apply an entry

To apply a set of variables, click the row. Observability Platform compares the
stored keys to the list variable definitions on this dashboard to determine which
values to set. For details about how matching works, see
[Apply quick filters to list variables](/observe/dashboards/customization/dashboard-variables#apply-quick-filters-to-list-variables).

A confirmation message displays **Applied *N* variable** or **Applied *N* variables**,
where *N* is the number of variables applied. If no variables could be applied, an
error message displays instead.

### Favorite an entry

To mark an entry as a [favorite](/navigate/favorites), click the
**<Icon icon="star" /> favorite** toggle on its row.

### View the source page

To open the source page for an entry, hold the pointer over the row and click the
<Icon icon="ellipsis-vertical" /> menu that appears, then click **View source**.

### Save the current selection

To save the current variable selection as a named saved view, click
**Save current selection** at the bottom of the Quick filters dropdown. For details,
see [Manage saved views](/observe/dashboards/customization/dashboard-variables#manage-saved-views).
