Hide the panel

You can hide the panel and give the page the whole width of the window.

You’re reading a long Codeberg diff and want every column of it on screen.

  1. Press ⌃Z (Ctrl+Alt+Z on Windows and Linux).

The panel slides away. Press the same keys to show it again, with the focus on the tab you’re viewing.

You can also select Workspaces in the toolbar, or choose Hide Workspaces Panel in the menu bar’s Workspaces menu.

  • On a Mac, a web page can take ⌃Z for itself, as a terminal in a page does. ⌃Z then doesn’t hide the panel while that page has the focus.
  • You can change the keys in Settings › Keyboard shortcuts.
  • Each window shows or hides its own panel.
