Is there same as above key on a computer/laptop/smartphone? See detail.

Those two vertical lines ” are called ditto marks, and they use the double-quotes symbol. You can type that in a list and it means ditto the above.

It doesn’t cause the above entry to be duplicated. It just means “consider it duplicated” to the reader or viewer.

As for actually repeating the contents of the line or space above, for that you would just copy and paste.

I use Copy and Paste on my PC..
Highlight the text I want to repeat and hit CTRL C to copy it. Then move to where you want to paste it and hit CTRL V.
You can paste as many times as you like.

Thanks @kneesox and @LuckyGuy.

Also, is there a way of just copying the left or right part of the screen (a column for example I don’t mean for example ’‘Community Feed’’, here on the right, which can be done.
