Currently it is not possible to copy anything that isn't text on mobile. We currently have a 'Delete' button as selecting non-text items hides the keyboard (and the backspace button) so we should also add a copy button.

Previous task description:

Come up with a way to move/remove/duplicate focusable nodes in mobile

For plain text, most mobiles support cut/copy/paste and backspace through native means, however in the absence of a physical keyboard or direct access to the clipboard (for security reasons) this doesn't work with focusable nodes however we don't show a native selection when focusable nodes are selected. We should provide adequate editing capabilities via a sensible touch interface.

There are two approaches one could take (or some combination of the two)

Provide cut/copy/paste tools

Pros

• Users are already familiar with these tools, can achieve any moving/removing/duplication task through some combination of these
• Writing to the system clipboard is possible

Cons

• In order to paste anywhere, we would need to add a paste button to the toolbar (which is already crammed) or have via some less-discoverable technique.
  • All mobile devices have a native paste feature, we should assume that editors know about this.
• May need to add 'delete' as a fourth option if people aren't comfortable using 'cut' for that purpose.
  • This was added back in T62110
• Moving of block elements is less intuitive and does't show you valid 'drop' points
• 'Copy' and 'cut' are misleading in that they doesn't write to the system clipboard as well.

Provide move/remove/duplicate tools

Pros

• Also can perform any combination of move/remove/duplicate.
• A move tool could be intuitive to use on a touch device and could show 'drop' points
• Duplication is a one-click process
• Clearer that the system clipboard is not involved

Cons

• Users may be expecting cut/copy/paste terminology.
• Doesn't write to the system clipboard
• More complex to implement
