In NetBeans 7.4.0, when I double-clicked some words in the code, NetBeans highlights all of them (in my case, yellow). For clarity, and we hope to avoid any knees down, I do not mean the background color of the selected text or the text in the current line of the caret.

Having recently decided to change the colors of the editor (tools → options, fonts and color tabs), I was not able to find out the official name of this highlight with a double click to set the color. I looked through the entire list of options in the syntax, selection, annotation, markup, and version subheadings, without finding a record with a background color that seemed to match the double-click selection.
How to change the background color of this selected text with a double click?
