5. Using the Emulator Key-Log
This section explains how to use the Key-Log, which is a log of the emulator’s key operations. It 
also covers playback of recorded key operations and editing of Key-Log records. 
All of the operations in this section are performed using toolbar buttons.
I Key-Log File Structure 
A Key-Log file can contain multiple Key-Log records. 
Key-Log records contain recorded key operations, text and Main Memory data.

• You can assign names (up to 20 single-byte characters) to Key-Log records. 
Important!
• Key-Log data processing can take a long time when there is a lot of data. This is normal and does 
not indicate malfunction. 
• A key operation may not be stored to a Key-Log if you click it while an emulator calculation 
operation is in progress. 
Note
• Storage Memory data is not stored in Key-Log records.
• Opening the Storage Memory file during Key-Log playback can produce different results from 
those recorded to the Key-Log.
