After some tests with many different keyboards from f-droid, not a single one of the roughly 12 I tested were able to send capital letters. My workaround would be use a keyboard that allows for custom keys and add shift or a capslock input to the keyboard.
I tried "unexpected keyboard" which had the option to do this but i cannot for the life of me figgure out how to actually press capslock when its added to the keyboard its set to the letter A but its not useable through normal means i must have to hold it or something and i cannot figgure it out.
My other solution is to buy one of these
Its a dinky wireless keyboard with a left click on the top left making it holdable like a game controller and all mouse inputs are useable with only thumbs. Its great for using a keyboard from a bed or couch.
Best of luck
Using a pan and a propane grill are vastly different imo. I dont dislike charcoal or wood. I think each has thier own place depending on the meal you are preparing. For example I like to make steak and chicken kabobs on a propane grill and burgers and hotdogs on a charcoal.
At the end of the day though seasoning and meat quality take center stage. So its all about what you have access to and can afford.
