Addresses can be copied and pasted using the Windows clipboard.

Copying:

One or more addresses can be copied to the clipboard by selecting the address(es) from the Address List, and then using the Edit/Copy menu command.

Pasting:

Addresses can be pasted from the clipboard back into Handy Address Book.  The copy/paste feature allows you to quickly/easily duplicate addresses, or transfer any number of addresses from one address book to another.  When pasting addresses into Handy Address Book, all of the fields within an address are transferred.

Addresses may also be pasted as text into any application that accepts text, such as Notepad or Word.  When pasting an address in the text format there will be one address per line.  Each field in the address is tab delimited.  For text copying/pasting, the fields are placed in the same order as the columns in the Address List.  You can adjust which columns are displayed in the Address List, as well as their order.
