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"
    }
]

@greksak you must remove "count": 1, to make it works..

... no we still have not ended world hunger

But on ST4 on MacOS, and inside the file Default.sublime-mousemap:

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

worked for me

For some reason, it works only on already opened tabs. If the tab is closed it does nothing. It worked before but at some point stopped. Any suggestions?

If you want VS Code style, like ctrl + button1 for definition and alt + button1 for selecting multiple lines, then paste this content instead:

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

macOS Default (OSX).sublime-mousemap in "~/Library/Application Support/Sublime Text 3/Packages/User/":

[
    // ⌘+LeftClick => goto definition
    {
        "button": "button1",
        "count": 1,
        "modifiers": ["super"],
        "press_command": "drag_select",
        "command": "goto_definition"
    },
    // ⌘+RightClick => jump back
    {
        "button": "button2",
        "modifiers": ["super"],
        "command": "jump_back"
    },
    // ⌥+LeftClick => set multiple cursors
    {
        "button": "button1",
        "count": 1,
        "modifiers": ["alt"],
        "press_command": "drag_select",
        "press_args": {"additive": true}
    }
