How to Cut, Copy and Paste in Android.

This looks simple but can be tricky sometimes when you use different apps. In general, these steps can be used in Email or some other apps:

Double-tap or touch-and-hold to select a word.
Drag the handles to adjust the area if needed, then tap Cut or Copy.
Tap an insert point, and drag the handle to adjust it if needed.
Select Paste (Hint: tab the handle when the 'Paste' button doesn't appear).

Note: When working in a web browser such as Android's Browser, use touch-and-hold to select a word since "double-tap" has been used to enlarge or reduce a webpage.
