# Find and replace code strings on the Advanced tab

> Find and replace strings in FlexiLayout language code with the Find in Advanced Code dialog box, searching the current element and all its subelements.

You can write expressions in the [FlexiLayout language](/flexi-capture/fls/code/general-code) to specify element properties, and you can specify [additional search constraints](/flexi-capture/fls/template/advanced-constraints) on the **Advanced** tab of the element's **Properties** dialog box.

Find and replace runs on the code of the current element and all of its subelements. To run it on the code of all elements, select the FlexiLayout (that is, the root element in the tree). To run it on only one layout alternative, select that alternative in the tree.

This feature is useful, for example, when replacing the name of an element, since you do not have to open the **Advanced** tab in the properties of each element individually.
