Add mouse click `goto definition` in sublime text 3.

goto-sublime

Linux - create "Default (Linux).sublime-mousemap" in ~/.config/sublime-text-3/Packages/User
Mac - create "Default (OSX).sublime-mousemap" in ~/Library/Application Support/Sublime Text 3/Packages/User
Win - create "Default (Windows).sublime-mousemap" in %appdata%\Sublime Text 3\Packages\User

[
    {
        "button": "button1", 
        "count": 1, 
        "modifiers": ["ctrl"],
        "press_command": "drag_select",
        "command": "goto_definition"
    }
]

I added another shortcut so ctrl+right-click will bring you back.

[
{
"button": "button1",
"count": 1,
"modifiers": ["ctrl"],
"press_command": "drag_select",
"command": "goto_definition"
},
{
"button": "button2",
"count": 1,
"modifiers": ["ctrl"],
"command": "jump_back"
}
]
