Screen modes (F) and hiding the panels (Shift-Tab), as in Photoshop

[Fvzion]

Best reviewed after #186: its one-at-a-time loader keeps people's custom shortcuts when new keys like F are added.

The problem today

There's no quick way to give the picture the whole screen. The only option is macOS full screen from the green button, which keeps every panel, and nothing hides the panels to look at an image uncluttered. Photoshop users reach for F and Tab without thinking.

What changes for the user

• F (on the canvas) steps through three modes, as Photoshop does:

  1. Standard: the window as you sized it.
  2. Full Screen with Menu Bar: the window fills the screen (menu bar and Dock stay) and the tab bar hides.
  3. Full Screen: macOS full screen; tools and panels stay.

  A fourth F returns to the window's exact previous size. Leaving full screen with the green button, ⌃⌘F or Esc also returns to Standard.

• Shift-Tab hides and shows the tool bar, options bar, Layers panel and status bar, in any mode. Plain Tab keeps its current meaning in Compositor (cycle the tool's mode), unlike Photoshop's.

• Both keys are listed in Keyboard Shortcuts and can be changed there. F is ignored while typing text.

How to try it

1. Open a picture and click on the canvas.
2. Press F three times, then once more: the window comes back to its size and position.
3. Press Shift-Tab, then again.

In the code

• New ScreenMode.swift: the modes and a small controller that remembers the window's frame and follows macOS full-screen notifications.
• EditorCanvas handles F and Shift-Tab; ContentView hides the panels.
• ScreenModeTests (9 tests), including a real window going in and out of the modes and keeping its size through the green button.

Can be trimmed

View › Screen Mode and View › Show Panels do the same as the keys. If you'd rather keep View short, they can go and the keys still work.

Tested on macOS 26.6 (Apple silicon): the full test suite passes. Not yet tried on macOS 27.
