I want to be able to column select in Sublime Text 2 on my HP Envy laptop (p/n: J4Z51EA#UUW) using the keyboard shortcuts Ctrl+Alt+Up or Ctrl+Alt+Down. By default, these shortcuts were used by Intel HD driver but that could be disabled using the Intel HD Utitity.
But back in Sublime, nothing happens when I press Ctrl+Alt+Up or Ctrl+Alt+Down. I have tried restarting my computer but that does not change anything.
