Tips

• Each Help menu item opens a separate dialog, so you can have more than one topic open at the same time.
• Press the standard Find shortcut (Ctrl+F on Linux and Windows, Cmd+F on macOS) while the dialog is focused to move the cursor directly to the Find: field.
• If a search term is not found, the Find: field border turns red and the status area shows "No matches". Clearing the field resets the state.
