Thanks for the tutor, that worked!
Just another brief explanation: With CTRL-G the user activates a column filter on each and every column that is displayed in the grid. The column filters together always work as an AND. Within each column it is possible to work with boolean expressions.
Here are some examples:
Filtering on a text string in the column "Klantnaam":

Filtering on a text string in the column "postcode":

Filtering on a text string in the column "Klantnaam" AND in the column "postcode" AND in "vervolgnaam 1" AND in "vervolgnaam 2" AND a boolean in "klantengroep" ruling out all records that have the string "EXT" in it.

To clarify: The results are always the same dbase record, as lazy me didn't make more than one test record in the dbase. But trust me, this works extremely fast and handy on master databases with hundreds of thousands of dbase records.
I think the mm4 filter is not as powerful and user friendly as it could be. Would this method (as you say, often seen in spreadsheets) be possible to implement?
