Solution 2, changing the setting of 200 rows temporarily:
When the Edit window has been opened you right-click on it and select Pane –> Sql like this.
This will open a Query box where you can change the SELECT TOP(nnn) statement used for editing. After changing it, click on the red exclamation mark (!) to update the selection.
As an extra bonus this method also makes it possible to select a subset of rows to be edited by using a WHERE statement.
