Create a programmable table (enable Switch Rows Programmatically) and name it "MyTable".
Go to each row of your table and name it in the Row Tags part of the properties; name them "Tab1", "Tab2", etc. for each of the "tabs".
Create an editable text field named "$MyTable" and hide this field from web browsers.
Enable "Generate HTML for All Fields" for the form.
You can then add clickable form actions to the form that do:
document.forms._doClick('$Refresh', this, null);
If you want to jump to a specific spot on the form, add an Anchor via passthru HTML that looks like this:
then call the _doClick function like this:
document.forms._doClick('$Refresh', this, '_self', '#MyAnchor');
Some of this is documented in Lotus Technote #173543 and there is a sample in the LDD Sandbox.
