IntelliJ line highlight color

Question

While working with IntelliJ, I used the shortcut incorrectly, and now I have a blue line with a backlight, which means nothing.

This is some kind of marker highlight.

How can I get rid of it? See Image.

Answer 1

If you were executing code using the debugger, the current line of the execution point would be highlighted in the same way (although the default color is different):

Stopping the debugger should delete the line.
