Option + left/right is awesome for jumping around quickly horizontally, but if you're like me, you've probably tried to use that same muscle memory to jump vertically by using option + up/down.
Here's a few macros you can use to accomplish that, as well as creating selections while jumping vertically as well.
Add these shortcuts and you'll be in bizniz:

{ "keys": ["alt+up"], "command": "run_macro_file", "args": {"file": "Packages/User/move_3_lines_up.sublime-macro"} },
{ "keys": ["alt+down"], "command": "run_macro_file", "args": {"file": "Packages/User/move_3_lines_down.sublime-macro"} },
{ "keys": ["alt+shift+up"], "command": "run_macro_file", "args": {"file": "Packages/User/extend_3_lines_up.sublime-macro"} },
{ "keys": ["alt+shift+down"], "command": "run_macro_file", "args": {"file": "Packages/User/extend_3_lines_down.sublime-macro"} },
