Create ability to write keyboard macroses. For example I have following lines:
column1 as varchar(100),
column2 as int,
...
column117 as uniqueidentifier primary key

I want to get all column names. What I usually do, I am copying it to external editors that support macroses and record it on the first line with following actions:
holdctrl+right(cursor goes to the end of column name), holdshift+pressendbutton (highlights entire row),pressdel (to delete this text),press,(to add comma at the end),pressdown(to go to the next row),presshome (to return at the beginning of the second row)
Then I replay this macro and I have just column names.
