You might not have to switch modes.
If the mobile mode has a cursor, hover it to the right of the “Flag as…” button at the bottom of an answer.
If you look at your own answer, place the “cursor” to the right of the “Edit your response” link there.
This should reveal a ¶ character.
If you place the “cursor” over that character, you should get a popup that says “Permalink for this response (elapsed time since response)”.
E.g., if I place my cursor over the ¶ in your answer, I get one stating, “Permalink for this response (2 hours ago)”.
