While you are in the Schema Editor, Column or Tree view, you can do right click on a table and in the contextual menu choose GenerateSQL -> Insert / Update / Delete.
You will be asked to specify fields for Insert / Update commands, after that you will see SQL Editor with generated command. You still need finish it of course in VALUES() section for INSERT, and SET section for UPDATE command.
Anyway this feature can save you couple of minutes of job per each such command.
