Inserting CheckPoint

当用户想要插入一个检查点时，必须确保在录制期间仅支持大多数检查点。一旦用户停止录制，检查点将不可用。

When the user wants to insert a checkpoint, one has to ensure that most of the checkpoints are supported during the recording sessions only. Once the user stops recording, checkpoints are not enabled.

以下是在非录制模式下，检查点菜单。

Given below is the checkpoint menu, when the user is NOT in the recording mode.
