Office2 lets you copy portions of a document and paste them either elsewhere within the same document or within another document.
To copy a portion of the document, first select the portion of the document that you wish to copy. A menu will appear showing the words: Cut, Copy and Paste. Tap the Copy menu item.
To paste what you have copied, first position the cursor by tapping and holding to ensure the cursor is at the appropriate insertion point. When you release, another menu will appear, showing the words: Select, Select All, Paste. Tap the Paste menu item.
The contents of the copy buffer will then be pasted at the insertion point that you have chosen.
