I recently started using Apple Intelligence, which wasn’t available in my country before. Though the writing tools aren’t customizable yet, the proofread functionality is useful.
I wish there was a shortcut to recall writing tools from any text area instead of right-clicking the selected text.

Exciting to hear about your experience with Apple Intelligence! It's great that the proofread feature is helpful. A shortcut for writing tools accessibility would definitely enhance the user experience. Your feedback is valuable for improvement.
