I hope to be leining megilla for the first time this year. Anyone have any tips or information on different minhagim that I may not be aware of?
The best tip is to practise, every word of the megila is meakev so make sure you can read corrrectly every single word. There are different minhogim but most are the same by everyone.
•raise your voice by בלילה ההוא
•we repeat ואיש לא עמד בפינהם and להרוג ולאבד first time we say בפניהם second time לפניהם, first time להרוג second time ולהרוג.
• certain places we do eicho tune
• shake the megila by איגרת הזאת, איגרת הפורים הזאת.
Shulchan oruch mentions most of them so take a look.
• we make the last brocho davka before the megila is rolled up.
I'll write some more as I remember.
