The OCR condition (v9.0+) extracts the text from an image using OCR (Optical Character Recognition) (specifically using the Tesseract OCR library) and determines if it currently meets the specified.
The source image can be pasted into the action, or read from the System Clipboard, Trigger Clipboard, a Named Clipboard, or a file, or you can get the image from the screen.
When reading from the screen, you can get the image from all screens, or from a specific screen or window or area on the screen.
You can choose what language or script the text is in. Each language will require a download, typically between 1 and 10 MB, though there are a few scripts that are significantly larger.
You select the comparison criteria in the popup menu.

As with any OCR, the text may contain errors so you should be relatively liberal in how specifying your criteria.
