### 3.4.5 The Toolbox menu

The Toolbox menu contains commands that are used to insert operators into the session. This menu includes the following entries:

- New entry (Alt+N)
  This will insert a new level after the current one.
- New comment (Alt+C)
  This will insert a new comment level after the current level.

The other entries allow you to insert mathematical operations into the current level. When you do that, you will also be taken to the help index (See help index ) with help on the chosen command.
