Selecting text
You must select text before you can edit it.
To select text:
In Browse mode or Find mode, position the pointer over any selectable text.
In Layout mode, use the Selection tool Selection tool in the status toolbar to manipulate a block of text as if it were an object. For example, copy or move it, change fonts, or resize it (which changes the margins of the text). When a text block is selected with the Selection tool, typing replaces the text in the text block.
In Layout mode, use the Text tool Text tool to edit text. You can also double-click a text block with the Selection tool to edit the text.
