The command "xev -event ${event_category}" is used to launch the xev tool with a specific event category.

xev is a utility in Linux-based systems that allows you to monitor and analyze events generated by the X window system. This tool can help you understand and troubleshoot input-related issues, such as keyboard or mouse events.

The "-event" option is used to specify the event category to monitor. The ${event_category} is a placeholder that should be replaced with the actual event category you want to observe. For example, you could use "KeyPress" to monitor key press events or "ButtonPress" to monitor mouse button press events.

By executing this command, xev will start a window that captures events of the specified category, displaying detailed information about each event as it occurs. This can be useful for understanding the event flow and properties when a specific action is performed.
