If you mean you want to click on several different records and have them all
active at once (or you want to copy them all at once), the answer is there is
no method to do this.
If you mean you want to mark several different records and then do something
with them there are two methods that I can think of.
Method one: best used in single-user databases
Add a field to the table (usually a checkbox) and show it on your form. Then
use it to add or remove records from the selection. Then use a query or a
filter to choose just the marked records.
Method two:
Add a TABLE (work table) with two (or more fields)
Field1: contains the primary key of the Source Table
Field2: contains an identifier (userid or an arbitrary session value)
Have a button on your form that will add/remove the current record to/from the
work table.
