The desktop

The home screen

Before the first message, the home screen is a desktop. Icons stand in columns down its left edge: the project, Changes, Sessions, the Finder, Models, Themes, Settings, Wallpaper (pick the picture behind everything) and Welcome (the first-run walkthrough again). The card in the middle says what Friday runs on and offers three requests to start from. The tour's scenes play in a panel on the right, and stay there down to a laptop's width.

• ↑ on an empty input steps onto the icons. The arrows move between them and enter opens one.
• tab puts a starter request in the input. Nothing is sent until you press enter.
• A click selects an icon, and a second click on it opens it.
• esc, ↓ past the last icon, or typing goes back to the input.

Windows

Each app opens as a window floating on the wallpaper. Its body is frosted glass: the photo behind it, blurred and tinted, so the text stays readable and the picture still shows. Its title and two buttons sit in its top edge: ▢ zooms it to the whole space between the bars, ✕ closes it. A second click on the title zooms it too.

A window's keys are buttons along its foot. A click on one does what the key does, so nothing is out of reach of the mouse. Anything you browse is a window and gets a tab in the top bar: Files, Changes, Sessions, Models, Themes, the wallpaper, Help, the Finder, Settings, Providers, Stats, Tasks and Keys. A dialog is kept for a question that has to be answered first: an approval, a confirmation, connecting a provider.

One grammar

Panes work the same way. In Changes, ← and → move between the file list and the diff; on the diff, ↑ and ↓ pick a line and enter comments on it. In Files the wheel moves through the tree on the left and scrolls the preview on the right.

The bars

The top bar holds a tab for each open window; the dock along the bottom holds every app with its key. From a window's top level, or from an empty input in Chat, esc steps out to them, and they become one row the arrows walk along:

• ← and → move along the tabs and then the dock's apps.
• enter switches to a window or opens an app.
• delete closes the window under the cursor.
• ↑ or esc goes back into the window. Any other key goes back too, and is kept: typing is never lost on the way.

The conversation

In Chat, ↑ on an empty input steps onto the newest block of the conversation: what you said, what Friday said, or one of its tool calls. A bar in the margin marks it.

• ↑ and ↓ move from block to block, and the view follows.
• enter on a tool call shows its whole output, and enter again folds it. On a message it opens a reader.
• space reads any block in a reader, where it can be searched and copied.
• ↓ past the newest block, esc, or typing goes back to the input.

Earlier messages, which ↑ recalled before, are ctrl+↑ and ctrl+↓.
