[Lazarus] TDBNavigator button click

[andtag]

Hello,
I have a DB with 400 records and clicking the next button i can see the
next record. If i want to reach record 200 i must do 200 clicks.
I want to have a continue action pressing the dbnavigator button, for
example, when i click Next button, i want the records go forward until i
leave the button. Is possible to do?
Any solution is welcome for do what i need, please... maybe with normal
button: exists a function for know if a button is pressed down, not only
a click?

Andy.
