# DelListLine

Deletes an entry from a list. If the entry occurs more than once in the list, you can choose to delete either the first instance or all instances.

This action is synchronous. IDOL Speech Server returns the number of lines that it has deleted.

## Example

    http://localhost:13000/action=DelListLine&Key=phrases&Line=Global financial markets&Once=True

This action uses port `13000` to instruct IDOL Speech Server, which is located on the local machine, to delete all instances of the line `Global financial markets` from the `phrases` list.
