# Details sidebar

Clicking a row in the catalogue opens a sidebar for that variable, like the page panel elsewhere in Capable. The open row stays highlighted. The header shows the variable's name with **Edit**, **Delete** and **Close panel** buttons.

## Editing

1. Select **Edit** in the sidebar header (or in the row's **...** menu). The details turn into a form.
2. Change the name, value or description. The type cannot be changed.
3. Read the notice: _Saving changes the text of every page that shows this variable, including pages you cannot edit. Those pages get no new version and watchers are not notified._
4. Select **Save**. You see **Variable saved**.

The form loads a fresh copy when it opens and checks again just before saving. If someone else saved in between, it shows their value and asks you to apply your change again. See [Someone else changed this variable while you were editing](https://help.gocapable.com/variables/someone-else-changed-this-variable-while-you-were-editing.html).

---

## Deleting

**Delete** asks you to confirm and tells you how many pages that you can see use the variable, warning that they will show \[unavailable\]. Deleting moves the variable to the space trash. See [Retire or replace a variable safely](https://help.gocapable.com/variables/retire-or-replace-a-variable-safely.html).

## A few things that catch people out

* The usage count only includes pages you can see, and pages published in the last few minutes may not be counted yet. A count of zero does not prove nobody uses the variable.
* Edit is greyed out when your permissions or the variable's restrictions do not let you change it.
