LineHighlight is a simple open source bookmarklet for persons with dyslexia that highlights (in yellow) the text line the user clicks on in a web browser. It has been developed by Erik Zetterström and funded by ICT Enablers.
It is intended as a tool primarily for persons with dyslexia, but can be useful for other purposes as well.
Drag this button to your bookmarks bar:
When you wish to use it, just click on the bookmark. You will see a little yellow box saying “LineHighlight” in the lower right hand corner when LineHighlight is active.
If the button does not work in your browser, manually make a new bookmark called “LineHighlight” with the following address:
Bugs and known issues
LineHighlight runs on the latest Firefox, Google Chrome, Opera and Safari browsers. Internet Explorer is not supported because it lacks support for the selection.modify() function.
When clicking on for example bold text in the middle of a row only the bold text will be highlighted because the selection method sees the bold tags as line boundaries. Keep in mind that the software is just released, so there are surely bugs. Bug reports and feature requests are most welcome.
Given free time and funds these are the top 3 features I would like to add to LineHighlight.
