kLED

There are some details about your system you may want to have access to without putting any effort in the process. For instance, checking the status of Num, Caps, or Scroll Lock at a glance is something that could prevent you from making any tests in order to ensure everything is how you expect it to be.

kLED is a lightweight piece of software you could turn to in this regard and that offers to bring close at hand various info on these aspects right in the system tray.

Before anything else, it is worth pointing out that kLED requires no installation, and you can have it up and running simply by double-clicking its executable. Once you do that, a new icon pops up in the systray, offering access to the data it can collect without clicking on it.

To be more specific, the symbols the icon comprises show you whether Num Lock, Caps Lock, and Scroll Lock are on. The way it does that is by changing the color of the corresponding initial for each enabled functionality in part: N, C, and S, respectively.

Aside from that, you may want to know that there are multiple icons you can choose from, namely Cubes, Diagonal, Horizontal, and Vertical. In terms of configuration, that should be it if you don’t want to bother with more subtle aspects.

On the other hand, those of you who don’t mind looking into advanced settings can do so. As such, all you need to do is modify the config document you can access by right-clicking the app’s icon. Here, you can change the foreground and background color, the font name and size, screen coordinates, and display timeout without restarting the program.

On an ending note, kLED is a tiny tool you could turn to in order to check the Caps, Num, and Scroll Lock status simply by taking a look at an icon in the systray. The program requires no setup and does not interfere with your workflow, so you may find it pretty useful.
