- On: the same pages, with the technical sections open. Values that are otherwise only a tooltip appear as a line in code font. A tinted strip says: “Developer view: technical detail is shown everywhere. Press D to turn it off.”
Turning it on
- Use the switch at the top right of every page of an app, on Your apps and in Settings.
- Or press the D key. It does nothing while you type in a field, or with Cmd, Ctrl or Alt.
- In Settings › Profile it is called For developers: “Show file names, routes and technical details next to plain words.”
