Column/Block selection using keys


I was a long time user of TextPad editor and the one feature I loved was how you could do column selection with your keys especially the ability to select a column all the way to the end of the file.
i.e. you would select from position 6 to 15, say, on the first line and if you hit ctrl-shift-end after that it would select that column all the way to the bottom of the file w/o having to use your mouse to drag and hold all the way to the last line.

I installed the sublime-style-column-selection package but all that lets me do is use the alt-left-mouse to select the column, but I still have to drag the selection all the way.

Is this something that’s available in Atom and I just don’t know how to use?
