Copy & pasting

I am having trouble in my exercises pasting links that are a part of the exercise i on the p[revious page the same thing occured i looked in the forums and found advice about switching tabs from style/css to index/html but it still is not allowing me to paste on my exercises this is very frustrating someone please help

Maybe the keyboard shortcuts would help?

On my Windows computer,
Ctrl+C to copy (after selecting the appropriate text)
Ctrl+V to paste (after clicking on [or moving to] where you want it to be pasted)

I think it’s Cmd instead of Ctrl on a Mac.
