Comment 1 for bug 1786727

I can confirm that 'C' doesn't do a copy with either Toolset (the text layer isn't material).

I can't reproduce the "fills zones" issue in the Modern Toolset. You might need to reset your hotkeys.

With the Modern Toolset there are additional issues:

Select a PCB text item.
Right-click > Copy
Move mouse somewhere else and click.
Ctrl-V
Don't move mouse: can't see pasted text item.
Move mouse: pasted text item appears.

Select a different PCB text item.
Right-click > Copy
Move mouse somewhere else but do NOT click.
Ctrl-V
Move mouse and note that wrong text was pasted (it's the first one)

Select a different PCB text item.
Right-click > Copy
Move mouse somewhere else and CLICK.
Ctrl-V
Move mouse and note that correct text was pasted.
