Line Reader turns your mouse into a helper line, to easily guide your eyes while reading long documents.

Have you ever felt completely overwhelmed by pages and pages of online text, like what you find in research papers, news magazine articles, and technical documentation?

As you scroll through these long documents, you find yourself losing your spot, rereading the same sentences over and over, and generally causing headaches, disorientation, and burnout.

What if there was one simple application that could help guide your eyes while reading, making digesting long electronic documents easier and more efficient? That’s the core reason behind Line Reader, along with a few bonus features that will make this app an indispensable part of your user experience!

Line Reader addresses a dilemma that we all face at some point – how to manage reading long documents online.

If we were reading a book or printed article, we could use an index card to mark our place and guide our eyes as we read. Since holding an index card up to your computer screen is impractical, we’ve created Line Reader to navigate you through the rough waters of electronic documentation.

With Line Reader, your mouse cursor transforms into a handy reading aid, taking the form of a horizontal line that you use to track your spot in any online document or web page. You can customize the length, width, and color of your line, as well as invoke a secondary helper line that serves to further emphasize the location of your cursor.

One click, and your line flips to the vertical, which is convenient for highlighting entire paragraphs, steps in a recipe, or assembly instructions.

As amazingly useful as Line Reader is, we’ve made it even better by including some handy bonus features! First, there’s the Magnifier Window, which offers an enlarged view of anything that you hover your line cursor over and a screen grabber. Then there’s the Measurement Window that gives you the ability to measure anything that you can see on your computer screen. Finally, we have the Tag Along Form Window, a resizable, customizable box that attaches to your line cursor and serves as an appointment reminder, image holder, or text box!

Version 2 of Line Reader now includes saved profiles, a multiline capability, keyboard nudge control and auto scrolling lines. We've also added the capability to change the way the line itself functions, inverting the text beneath it, or using a number of graphical effects. Just take a look at our videos of Line Reader in action and you'll see how useful this application really is.

    Other things to consider:
  • it's possible at some point to realize that the LEFT, RIGHT and MIDDLE buttons appear not to be working and this happens because:
    • STEP 1: you started with a normal horizontal line reader with values for example: Width=200 and Height = 2.
    • STEP 2: Then you flipped it and thus the Width is now 2 and the Height is now 200. Then while the line reader remained flipped you changed the Width = 200 and Height = 2 which gives the impression that the line is horizontal again (even though it is actually flipped).
    • STEP 3: So when pressing the LEFT, RIGHT and MIDDLE buttons the line doesn't seem to be moved LEFT or RIGHT or to the MIDDLE.
    • STEP 4: However, the line is moved and to see this you have to increase the Height and set it to a bigger value than 2, for example: 50 and then you will see that the buttons are working.
  • the tag along windows content like many other properties of the line reader are saved when quitting the form
  • to access the tag along windows you should use the ALT + TAB key combination from Windows and then once the tag along window has the focus you can use the TAB key to "tab" through its contents.
