# Use keyboard shortcuts
Source: https://docs.aden.space/docs/help/start-here/preferences/keyboard-shortcuts

Learn the shortcuts that matter, remap any of them, and undo a delete with one key.
## Shortcuts to know [#shortcuts-to-know]

* **⌘K**: search and commands
* **⌘B**: show or hide the sidebar
* **?**: see every shortcut
* **⌘Z**: undo the last delete

On Windows and Linux, use **Ctrl** instead of **⌘**.

## Remap a shortcut [#remap-a-shortcut]

1. Open **Account → Shortcuts**.
2. Click the binding next to an action.
3. Press the keys you want, then save.

To go back to the default, delete your custom binding.

## Undo a delete [#undo-a-delete]

Deleting something removes it right away and shows a message with **Undo**. You have five seconds to take it back. Delete several things in a row and one message covers them all.

Press **⌘Z** instead of clicking. It undoes the newest delete first, unless you are typing in a field.
