# Finding unused and incorrectly used keys in property files

Finding unused and incorrectly used keys in a property file:

- Open the Search dialog by:
  - pressing `Ctrl`+`H` or
  - selecting Search > Search from the menu bar
- See if a tab called NLS Keys is visible. If it is, then select it.
- If it is not visible, press the Customize button and select the NLS Keys checkbox, press OK to close the dialog and switch to the NLS Key tab.
- In the Resource bundle accessor class field, enter the name of the class that you use to retrieve strings from the property file. You can use the Browse button to select the class from a list.
- In the Property file name field, enter the name of the property file. You can use the Browse button to select the file.
- Select the scope of the search by using the controls in the Scope group.
- Press Search

After the search is finished, the Search Result view displays a list of unused keys in the property file and all incorrect references to non-existing keys.

Note: This feature assumes that the resource bundle accessor class used a method called getString with a single String parameter to retrieve strings from the property file.
