If you have a uicontrol style 'edit' (traditional figures), or if you have a uitext (uifigures) and those have text in them, then matlab does not provide any way itself to find out what text is selected.
The same is true for edit fields.
You can find out which cells of a table are selected, or which entries of a list box or drop box are selected, but not what text is selected within a field.

Attached is one where I hide an image. You can adapt it to hide text if you want.

That demo does not hide a gray scale image in another gray scale image. It only uses the cameraman gray scale image to create the binary image. It is actually the binary image that I'm hiding, and there is no data loss for that. I just made this demo a long time ago following what one poster said he wanted to do. If you have a version that hides a grayscale image inside another grayscale image, please post it.
