to type a number: alt + number

Explanation:

The problem involves a verb "to study" and likely requires providing its conjugation or translation in a language (possibly Spanish, given the special characters like á, é, í, ñ, ó, ú, ü, ¿, i). For example, in Spanish, "to study" is "estudiar". If we assume it's about conjugating or writing the correct form (maybe in a language context), the relevant subfield is Languages (under Arts).

Answer:

estudiar (assuming the task is to provide the Spanish infinitive form of "to study" matching the language - related context with the given special characters)
