For the vi mapping:

exports.VimKeyMapping = StandardMapping.create({
    states: {
        start: [
            {
                name:   'Delete n lines',
                regex:  'd([0-9]+)d'
                action: 'deleteLines'
            },
            {
                name:   'Enter insert mode',
                regex:  'i',
                then:   'insertMode'
            }
