keyboard shortcuts - Can I get Notepad++-style vertical selection with arrow keys in Sublime or Atom?

In Notepad++, I'm used to using Alt+Shift+↑/↓/←/→ to put expand the cursor across multiple lines in a vertical line or rectangular selection. I think Visual Studio does something similar.

I'm trying Sublime and Atom instead. Ctrl+D, Ctrl+click, and Alt+click + drag are very cool, but I miss using the arrow keys to make my vertical selections.

Is there a way to do vertical/rectangle selects in Sublime Text 3 or Atom with the arrow keys? I'm open to installing packages.

Example

1. Say I have this (│ represents the cursor, ignore the spaces in that column):

   
   

   x = os│.join(a, b)
   y = os .join(b, c)
   z = os .join(c, d)
   




2. I realize I forgot the module name, so I hit Alt+Shift+↓+↓ and have:

   
   

   x = os│.join(a, b)
   y = os│.join(a, b)
   z = os│.join(a, b)
   




3. I type .path and now I have:

   
   

   x = os.path│.join(a, b)
   y = os.path│.join(a, b)
   z = os.path│.join(a, b)
   

I'd like to do the second step in Sublime Text 3 or Atom.
