How to edit the text contents using smart object.
I want to know how to edit the text contents using smart object and
what I want to do is to edit just 1 letter of text content so in this case I'm not considering the way to transform whole text.
What I tried to edit the contents was to rasterize that layer but even after doing so
I was not able to revise text contents.

What I'm confused with is that after making the layer smart object, you lose the chance to edit the text contents
and also the icon T standing for text is gonna be changed into gray and white background icon like sample layer in this picture.
What does is stand for ?
Does it mean that background is transparent ?
Thank you in advance for your help.
