I want to have a keyboard shortcut key for opening the same file in another tab.
this can be done using File>Split view
How can I create a keyboard shortcut for this
{ "keys": ["ctrl+u", "ctrl+s"],
"command": "clone_file",
"args": {"add_to_selection": true} },
BTW, I found the command's name by typing sublime.log_commands(True) into the console. See OdatNurd's excellent video on this: P101-03 Tools of the Trade: Harnessing the power of the console!
