# Top Display

Top Display is a small macOS PDF presentation viewer. It opens PDF files, displays one page at a time, supports quick navigation and zooming, and lets you draw temporary laser ink over the page while presenting.

## Controls

- Drag on the PDF to draw laser ink. A first-use hint appears until laser ink is used.
- Space or Right Arrow advances to the next page.
- Shift-Space or Left Arrow goes to the previous page.
- Home jumps to the first page.
- End jumps to the last page.
- Escape exits full screen.
- Cmd+, opens Settings.

## Settings

Settings controls the laser pointer color and the PDF pin position. PDF pinning supports nine positions, with Top Center as the default.

## PDF Behavior

Top Display treats PDFs as read-only presentation documents. It does not save or modify PDF files. Reload PDF refreshes the open document from disk while preserving the current page when possible.
