For it's time, the menu option above were considered reasonably complete. However, today's language IDE's are considerably more complex.

Search Menu
The Search menu provides the following options. Keystroke shortcuts are shown in the image above.

• Find - Starting at the current cursor position, locates the next occurrence of a string. The search may be case sensitive and/or limited to a "word search (text string bounded on both sides by spaces, start of line, or end of line).

• Repeat Last Find - Repeats the search using the last entered search string. Starts at the current cursor position.

• Change - Replaces the search string with a specified string. Replacement of each occurrence can be confirmed, or all occurrences can be replaced at one time.
