No shortcut for 'Export selected entries to clipboard'?

In older versions, it used to be very simple to do an export of entries to clipboard with a right click on the mouse.
This feature has disappeared and I miss it a lot.
Alternatively, adding the icon in the toolbar would be very helpful (the icon already exist from what I understand when I go to Edit menu,but I cannot figure out how to add it in the toolbar)

You are aware that you can just select the entries in the main table and copy them with CTRL + C and paste them with CTRL + V?

This copies/pastes the whole bibtex code for each entry
