In Eclipse Helios I want to highlight selected lines using a custom background color, like one would do with a text marker for normal text on paper.
How can I do tha
Yes, there is. Atleast as a workaround.
Mark a line as a bookmark; Right click on the line number field in the java editor, choose "Add bookmark" The go to preferences; General - Editors - Text Editors - Annotations. Choose bookmarks in the table, select "Text as highlighted"
