How to get table out of SetKey mode into Edit mode?

I have an application which performs a search on form1.  I retrieve a
key and using that key on form2, I locate the desired record in a
table.  The table is in dsSetKey mode.  I need to get it into Edit mode
to modify specific fields.  Any ideas?

I am using Delphi 2.0 c/s on a SQL database.

Thanks for any and all pearls of wisdom.
