Safari Extension
Archived legacy instruction page rebuilt as a lightweight static page.
This page explains how to use the Single Tap Highlight Extension (PPL).
If you came from a window launched during installation instead of Safari, please copy the following URL into Safari and open it again.

These links point to the maintained legacy support pages under `/backups/`.
By simply tapping on a word in a sentence, the same word is automatically highlighted with the same color.
At first glance this may look trivial, but it can significantly help track repeated terms and improve readability in dense text. It is especially useful for foreign-language study, academic papers, textbooks, qualification exams, and legal documents.
The key idea is that you can keep reading naturally and interact with the text by tapping, without interrupting yourself for separate search or keyboard input.
This page is a simplified static replacement for the older Drupal-derived `STHE` page. The goal is reliability and readability within the current minimal site structure.
