I want to copy the output of a command in https://www.geogebra.org/graphing and paste it in form on another web page. Left clicking does not provide the option. Ctrl c does not do it.
How do I copy output? Is there some hidden shortcut like Ctrl c
I can't even copy input in expressions. I can only copy text input.
The same question 
select the square at left of output and press F4 then copy and paste the last cell
I'm not sure if I understand you well. If you want to repeat the output of a command in another file, I guess the logic way is to copy paste the command you typed in the new file. If you use an app or GG6 without inputbar, you can rightclick on the output and copy the command from the properties.
I don't understand 'paste on another webpage'. So wher are you working in and where do you want to recreate something?

Have you tried <Ctrl>C in Chrome?
