Edit List of Accounts Tab
There are two ways to populate the accounts that you want
to update globally in the Edit List of Accounts tab. One is by
manually entering or selecting one account at a time from the normal
Account lookup 
, the other is by
using a special multiple value lookup called the Look Up / Add Multiple
Account Lines to return
multiple values.
For information about how to use
the multiple value lookup, see Multiple Value
Lookup.
