Feature: start from table completion

[rklak]

I would like to speed up query building process. Most of the time i need to write SELECT * FROM tableName and than come back to * to have autocompletion for columns.

It will be nice to type sth like {prefix} tableName to get table autocompletion and after hit some keystrokes(< TAB >, < ENTER > whatever) it will expand to SELECT * FROM tableName witch caret at *.
