Issue found while translating NVDA.

Link to issue number:

Follow-up of #13435.

Summary of the issue:

In fake table navigation in list views, horizontal movements only move the navigator object, whereas vertical movements move the navigator object but also the focus. This was not reflected in input help for the newly introduced commands to jump to first/last row.

Description of how this pull request fixes the issue:

• Updated the two scripts documentation.
• While at it, I have also converted remaining fake table navigation scripts to syntax with decorator.

Testing strategy:

Manual tests:

• Checked input help
• Checked that all fake table navigation still work in the detailed view of processes in the task manager.

Known issues with pull request:

None

Change log entries:

Not needed (fix in dev stage).
