Atom/Sublime like Multiple selections in Jupyter

问题

How can I select matching keywords in a Jupyter notebook via a keyboard shortcut? For example, in the Atom/Sublime editor I can hit cmd + D on a mac (or Ctrl + d on Windows) while the cursor is over 'var' and each time I do that the next 'var' will be highlighted. I can then type the new variable name and 'var' is replaced with whatever I typed.

var = "hello"
print(var)
print(var)

Is there an equivalent in a Jupyter notebook?

回答1:

Add custom.js to

C:\Users\username\.jupyter\custom      # for Windows and 
~/.jupyter/custom/                     # for Mac

with content

require(["codemirror/keymap/sublime", "notebook/js/cell", "base/js/namespace"],
    function(sublime_keymap, cell, IPython) {
        cell.Cell.options_default.cm_config.keyMap = 'sublime';
        cell.Cell.options_default.cm_config.extraKeys["Ctrl-Enter"] = function(cm) {}
        var cells = IPython.notebook.get_cells();
        for(var cl=0; cl< cells.length ; cl++){
            cells[cl].code_mirror.setOption('keyMap', 'sublime');
            cells[cl].code_mirror.setOption("extraKeys", {
                "Ctrl-Enter": function(cm) {}
            });
        }
    } 
);

and restart jupyter. Now Ctrl+D should work like it does in Sublime.

You can see that Ctrl-Enter functionality is disabled as it would be very convenient to run current cell rather than creating new line for most users. You can choose to have that functionality by commenting that line out.

You can disable other key config that you don't want in a similar way.
