All of these work in the preview. Zoom is anchored on the pointer, so the detail under the cursor stays under the cursor.
| Keys | Command |
|---|---|
| Z | Switch between fit and 100% at the pointer |
| ⇧F | Fit to the window |
| ⌥1 ⌥2 ⌥4 | 100, 200, and 400 per cent |
| ⇧Z | Lock or free zoom across Survey panes. Select/Candidate has a Linked Zoom control inside its view. |
A pinch on the trackpad zooms around your fingers, a two finger drag pans, and a two finger double tap does what Z does. In the grid, a pinch resizes the thumbnails.
