Thunderbird-mienskipsfoarum

I am on a MacBook M1 using Sequoia v15.3.1, running Thunderbird v128.7. I have been through many of the forums and also done Google searches, but have not been able to find a way to search for events in the calendar. When I am in the calendar and type a query into the search field, it will only search in messages. I have not found anything in settings that allows me to change this nor have I found any options available on the screen for searching only calendar events. I know there has to be a way that I am just not seeing. Also, there seem to be different options in view on the Windows version than in the Mac version and many of the solutions call for accessing a button or command that I don't see in the Mac version.

For several weeks I have been unable to search within certain emails i.e. Amazon, Jacque Lawson cards, Woot, etc. When I click within these emails to search for a specific item all I get is an"e" or an "i". I need (for example) to buy a specific item in Amazon but the email won't let me search for it. Extremely frustrating!!! I need to get this solved ASAP. Thank you. Linda Sullivan
