I've used a US-QWERTY keyboard layout my entire life. I've seen other layouts that do things like reduce the size of the enter/backspace keys, move the pipe operator (|) and can't wrap my head around how I would code on those.
What are your experiences? Are there any layouts that you prefer for coding over US English? Are there any symbols that you have a hard time reaching ($ for example)?
Just keep using the layout you're used to. I'm Brazilian too, but I've lived abroad my whole life, and US layout is what I'm most used to (even though I've never lived there, funny enough). When I'm on other keyboards, I just switch the layout to US International, and stop looking at the keyboard.
