thanks i hear it frequently, by english is clearly selfeducated by \.
This sounds for me exactly like rectangular selection. this will be in next release possible with keyboard too(hold alt+shift) but currently you should like i suggested hold Alt-Button and select this area with the mouse. than you can tread it like normal selection cut or copy or move by mouse. only the insertion isnt still perfect. it creates new lines and cant insert it in other lines but that feature will come too due its one of the fovourite of our designer.
please feel always free for suggesttions etc.
thanks
