cannot delete the text from restricted area

[kavithana]

Hello

I have the document similar to this



Type your text
Something is here
]

] is the tag in our document.

when we keep typing i can see the paragraph marks

Typing extra text
something i type and click Enter
Typed some text]

when i place the cursor before ] and press "backspace" then i can only delete "Typed some text"

Typing extra text
something i type and click Enter
]


how do i go back to "something i type and Enter"?
