PopTrayU Keyboard Lights Plugin

Given their reduced processing power, computers used to be operated through terminal layouts optimized for word processors and other data entry-focused programs. For information that needed to be inputted in highly detailed lists, the tabular format of spreadsheet applications was usually the most sensible approach.

Since the mouse and its scroll-wheel would be introduced at a later time alongside the development of graphical interfaces, navigating a webpage was done using the arrow keys. When typing, those same buttons would be used to move the cursor instead by toggling the Scroll Lock function.

Considering the low number of people still making use of what can be regarded as a legacy feature, the button has started to be omitted by manufacturers. Those who incorporate older keyboards equipped with this key into their workflows are also likely to bind it to a more frequently used shortcut.

The Scroll Lock function also features an LED light to let users know which functionality layer is active. One way to repurpose this element is through the PopTrayU Keyboard Lights Plugin, which turns it into a notification LED that lights up whenever a new email is received through the main app.

This particular approach lets users know when to check their inbox if their computer screen is turned off, similar to the notification LED present in older smartphones and flip-phones.
