Shortcut to change a line of words to a vertical list in Sublime Text 2

Question

Is it possible to make this title on line 1 a list of items from each word or symbol se

Answer 1

I adapted the above code for my own use, so that it now respects whitespace. But I hard-coded tabs instead of spaces, so if you use spaces you might have to change it further. It also now assumes you have no text selected and instead have the cursor in the middle of the line to be changed to vertical spacing. I left intro/outro as arguments so you can also use it for [] or (), although maybe some more escaping is needed in that case for the regex.

Before:

        fields = { 'Team1', 'Team2', 'Player1', 'Player2', 'Tab=Round', 'DateTime_UTC=DateTime', 'HasTime=TimeEntered', 'OverviewPage=Tournament', 'ShownName', 'Winner', 'Stream' },

After:

        fields = {
            'Team1',
            'Team2',
            'Player1',
            'Player2',
            'Tab=Round',
            'DateTime_UTC=DateTime',
            'HasTime=TimeEntered',
            'OverviewPage=Tournament',
            'ShownName',
            'Winner',
            'Stream',
        },
