Copy and Paste

please let me know why the copy-and-paste function doesn’t work properly!!

Hey @farzad_farzaneh we need more details about your problem

Hi @Tomasz_Przewlocki thank you for your time, my question is revolving around my task, in which I am trying to copy an element from one frame to another frame, with the short keys command + c; but by commanding the command + V short key the element doesn’t paste.

Can you send image what you want to copy and paste and view of Layer palette?
