Answer 1

CTRL+H does take two lines if you use regexp (and you don't have to write the regexp by yourself, eclipse does that for you).

1. Select your lines.
2. Click CTRL+H. The search dialog opens up. If "Regular expression" is already checked, eclipse will have converted the two lines you search for into regexp for you, click Search. If "Regular expression" if not already checked", check it and click Cancel (eclipse remembers your choise).
3. Select your lines again.
4. Click CTRL+H. The search dialog opens up. This time "Regular expression" is already selected. eclipse will have converted the two lines you search for into regexp for you, click Search.
