I'm not sure whether we still need KeyEvent... In this case it can be

input_stub_->SendKeyEvent(0, BACKSPACE, true);
input_stub_->SendKeyEvent(0, BACKSPACE, false);

perhaps, It might refactor out after I figure out how the meta mods will work.

+  // TODO(nicholss): Handle modifers.
+  // Key press.
+  keys.push({static_cast<uint32_t>(ui::DomCode::BACKSPACE), true});
+
+  // Key release.
+  keys.push({static_cast<uint32_t>(ui::DomCode::BACKSPACE), false});
+
+  return keys;
+}
+
+}  // namespace remoting
