Intro to formatting symbols in Pages on iPad
Formatting symbols (called invisibles) like the ones shown below are added every time you tap the Space bar, Tab, or Return, and when you add a column break, page break, or section break. On your iPhone or iPad, you can see most invisibles when you select text that includes them. All of the marks are visible in Pages on your Mac when you choose View > Show Invisibles (from the View menu at the top of your screen).
Nonbreaking space (Option-Space bar)
Line break (Shift-Return)
Paragraph break (Return)
Anchor point for objects set to Move with Text and any text wrap option except Inline with Text

The text is bookmarked
