Change middle mouse button in Sublime Text

In Sublime, create a new file with JSON syntax and the following contents:
[
// Mouse 3 column select
{
"button": "button3",
"press_command": "drag_select",
"press_args": {"by": "columns"}
},
{
"button": "button3", "modifiers": ["ctrl"],
"press_command": "drag_select",
"press_args": {"by": "columns", "additive": true}
},
{
"button": "button3", "modifiers": ["alt"],
"press_command": "drag_select",
"press_args": {"by": "columns", "subtractive": true}
}
]
Then, save the file as ~/.config/sublime-text-3/Packages/User/Default (Linux).sublime-mousemap. You should now be able to mimic the Windows middle mouse functionality in Linux.
