# lockText

`set [the] lockText of [ph:field] to [ph:trueOrFalse]`

The `lockText` property returns or sets whether the user can edit the text within a specified field. It corresponds to the Lock Text check box in a Field Info dialog box. The default value is false (meaning the field is unlocked).

When a field is locked, it can receive the system messages `mouseDown`, `mouseDoubleClick`, `mouseStillDown`, and `mouseUp` when the user clicks it.

Before a field can act as a [ph:list field], its `lockText` property must be set to true. 

## Examples

```
set the lockText of card field 1 to true
set the lockText of the target to false -- if the target is a field
set the lockText of me to true -- if in a field script
```
