Is there a way to use the keyboard to type Spanish letters with accent marks instead of clicking on them?
In WIndows, you need to add the "United States - International" keyboard layout under "Region and Languages" in Control Panel. You can then use: ~n to make ñ 'a, 'e, 'i etc to make á, é, í, "u to make ü RightAlt-/ to make ¿ RightAlt-1 to make ¡

this is likely still way to cumbersome, but on my mac I use the option + e to get the accent mark and then type the appropriate letter and i use the option + n and then type n to get the n with tilde, thus: ñ as far as bilingway, I've not figured a way away from clicking the is it an umlaut?
