Looking for words for any replacements or spelling correction in long texts is very simple in CorelDRAW. Go to:
Edit > Find and Replace > Find text (or Alt + F3).

In the pop-up window on the field "Find", type the text you need to find.
When there is more than one instance of the text you are looking for, click on "Find Next".
If you need to change the text use the option "Replace text" and type the text to be replaced.
