This summary is not the rule. The rule text controls.
If a judge makes a ruling during a trial or hearing, the lawyer or person involved does not need to say "I object" or formally announce that they disagree with the ruling just to protect their rights later. In many older court systems, you had to state a formal exception on the record right after a judge's ruling, or you might lose the right to argue about it later on appeal.
This rule gets rid of that requirement. All a party needs to do is let the judge know what they want, or what action they think is wrong, and why. As long as that request or objection is made clearly at the time, the person keeps the right to raise the issue later, even without using special legal phrases or formal language.
In short, this rule makes court proceedings simpler. People do not have to worry about using the exact right words or formal steps just to preserve their right to challenge a decision later. What matters is that they made their position known to the court at the time.
