# Searching and Replacing Text

You can search and replace text with the Search dialog by choosing Find from the Edit menu or clicking the Search button . You can also use the keyboard shortcut: `Control-Shift-%` in Unix, or `Control-F` in Windows.

This dialog enables you to search or replace text using different criteria:

- You must enter the character string for which you want to search in the Search for field.

- If the UPPER=lower button is selected, a case-insensitive search is performed; otherwise, the string is searched for as it appears within the Search for field.

- Strings can also be replaced using the same operation. You enter the replacement text in the Replace by field and select a replacement mode from the Replace box. The replacement modes are:
  - No replace: No replacement occurs even if the Replace field contains a character string. It is just a simple search.
  - Replace on request: When the string is found, Amaya selects it. The user can then click one of the following buttons:
    - Confirm to replace and carry out the search again.
    - Do not replace to search for the next instance without replacing the string that was found.
  - Automatic replace: All instances of the searched-for string are automatically replaced within the portion of document defined in the Search where box.

- The Search where box enables you to specify the part of document in which the search will occur:
  - Before selection: The search starts at the beginning of the selected part and moves backward to the beginning of the document.
  - Within selection: The search only occurs within the selected part, from its beginning to its end.
  - After selection: The search starts at the end of the selected part and moves forward to the end of the document.
  - In the whole document: The search is carried out in the whole document from the beginning to the end regardless of which part is selected.

To initiate the search operation, click the Confirm button at the bottom of the dialog. If Amaya finds the searched-for string, it is selected and the document is positioned so as to make this string visible. You can then search for the next instance of this string by clicking the Confirm button again. If the string is not found, Amaya displays a Not found message in the bottom right corner of the dialog.

Search or replace can be abandoned at any time by clicking the Done button.

Replacement operations can be undone by choosing Undo from the Edit menu, or by using the keyboard shortcut `Control-Z`.
