# Navigate Signal

This section covers how Signal is laid out on desktop, tablet and phone, and the global controls available from anywhere in the app: theme, the sidebar, and the command palette. It applies to every Signal user.

* [Tour the layout](/navigate-signal/tour-the-layout.md): Sidebar on desktop, collapsed sidebar on tablet, top bar and bottom tabs on phone.
* [Use the sidebar and bottom tabs](/navigate-signal/use-the-sidebar-and-bottom-tabs.md): Every navigation label and where it goes.
* [Collapse or expand the sidebar](/navigate-signal/collapse-or-expand-the-sidebar.md): The Collapse sidebar / Expand sidebar control.
* [Switch between light and dark mode](/navigate-signal/switch-between-light-and-dark-mode.md): The Dark mode / Light mode toggle.
* [Read the catalog loading bar](/navigate-signal/read-the-catalog-loading-bar.md): What "Loading asset catalog: X of Y" means and why counts grow after sign-in.
* [Why a menu item is missing](/navigate-signal/why-a-menu-item-is-missing.md): Optional areas that are off for your organization, and items that only Zephyr Intel staff see.
* [Use the command palette](/navigate-signal/use-the-command-palette.md): Ctrl+K / Cmd+K on Empire View: quick actions, asset lookup and brand filter shortcuts.
