LogiLockLED

Many times, you might accidentally press Caps Lock only to discover many words later that you need to change your lettercase all over again.
LogiLockLED is one of the apps that can display a notification whenever one of the Lock keys is pressed.

System tray app

Once you install it on your computer, the application sits in the system tray, meaning it does not clutter your taskbar with an additional icon. This way, you can focus on your work without being distracted by an over-crowded taskbar.
By right-clicking the system tray icon, you can easily enable or disable the functionality of the application.
Additionally, you can choose which of the Lock keys should be monitored. More specifically, the app can show the status of Caps Lock, Num Lock or Scroll Lock, and you get to select the way the on or off icons look like.

Customize on-screen notifications

Due to LogiLockLED, you can also modify the way its generated notifications look like.
You can change their position, by switching between center, top left, top right, bottom left or bottom right. Padding and margin values can also be altered. You can also check a box to get rounded corners for your notifications.
You get complete over the font type, size and style, as well as the color of the text and the background. Opacity and display duration can be adjusted just as easily.

To sum things up

In a nutshell, you can rely on LogiLockLED when you want to make sure you do not accidentally press one or several of the Lock keys. If you also happen to have a Logitech Gaming keyboard, you get additional functions.
