HeidiSQL Documentation

I am just starting to explore Heidisql.

Is there some sort of user manual? Here are some immediate questions:
What is the role of the tick boxes in the data view?
The data view shows a table with 4 rows but the database view shows that that the table has 3 rows.
I find that exporting a table and then attempting to import from the .sql file gives an error message.

What is the role of the tick boxes in the data view?

I'd say that it's basically to select rows and then remove them with the "Delete record" toolbar button.

The data view shows a table with 4 rows but the database view shows that that the table has 3 rows.

The database view information is cached. Hit the "Refresh" button or hit F5.

I find that exporting a table and then attempting to import from the .sql file gives an error message.

What error message? Whatever, make sure your export settings match your MySQL server version.

Thanks.
