Every once in a while I would open up a source file in Notepad++ to copy/cut text using the block selection mode. Now I can do it from within Eclipse (3.5 M5 and above). The block selection mode can be toggled using the toolbar icon highlighted above or using the shortcut key Alt+Shift+A. Nice addition to the Eclipse editor.
I would have liked it to work just like Notepad++ where I just hold down Alt key and do the selection in block mode but this would work too.
