Text Editor: Keyboard Shortcuts
sent here to whiteboards from GNOME/gnome-text-editor#638 (closed)
The HID is broken for use of Text Editor paired with Terminal. You have the situation where a whole document is copied and then pasted as executable code without the user intending to do so.
Whatever keyboard shortcut copies text from Terminal should (at most) do the same in other applications and no more that when pasted into Terminal would cause some unintended code execution. Re-use of that shortcut for other actions is not any problem so long as when a paste action follows into Terminal it does not do something unexpected.
