In IDEA you had the possibility to put your cursor on all lines.
Is this possible in Eclipse?
If you refer to the ability to select a group of lines (like a all function), you can use the outline view

From there, you can move/rearrange/delete all block of text.
If it is about column mode, see my answer here.
