  • Text to find
  • Replace with

These two fields contain the last searched text and replacement text (if any). will go back in history and will go forward in history and recall the previous search text and replacement text.


Tip: You can choose whether the Lazarus IDE starts the dialog with the word at the cursor in the source editor or with a blank field in Main Menu > Tools > Options > Editor > General > Miscellaneous > Find text at cursor.


  • Case sensitive - distinguish lowercase and uppercase (eg a and A).
  • Whole words only - the found text must start at a word start and end at a word end.
  • Regular expressions - treat texts as IDE regular expressions.
  • Multi line - the search does not stop at line ends or in other words: the found text can contain multiple lines. You can paste/copy multiple lines from the source editor to the Find field and you will see the line endings. These line endings cannot be created by normal keys. When searching with regular expressions you can use \+n (backslash plus n) as marker for line end characters. This also activates "multi-line" reg-expression option: for example, reg-expression "begin.*Application" will find such text:
  • Prompt on replace - ask before replacing (only enabled if replacing).


  • From Cursor - start search at the cursor. If direction is forward, it searches until the end of the file.
  • Entire Scope - start search at the text edge (at the beginning for forward search, at the end for backward search)

Search Scope

  • Global - search in the whole file.
  • Selected Text - limit the search to the selected text.

Tip: To search multiple files at the same time, use Main Menu > Search > Find in files.


  • Forward search - search top to bottom. Each line is searched from left to right.
  • Backward search - search bottom to top. Each line is searched backward from left to right.
