For anyone else who wants to set Eclipse style goto definition, you need to create .sublime-mousemap file in Sublime User folder.
Windows - create Default (Windows).sublime-mousemap in %appdata%\Sublime Text 3\Packages\User
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
Now open that file and put the following configuration inside
[
{
"button": "button1",
"count": 1,
"modifiers": ["ctrl"],
"press_command": "drag_select",
"command": "goto_definition"
}
]
You can change modifiers key as you like.
Since Ctrl-button1 on Windows and Linux is used for multiple selections, adding a second modifier key like Alt might be a good idea if you want to use both features:
[
{
"button": "button1",
"count": 1,
"modifiers": ["ctrl", "alt"],
"press_command": "drag_select",
"command": "goto_definition"
}
]
Alternatively, you could use the right mouse button (button2) with Ctrl alone, and not interfere with any built-in functions.
