Translation guide
The English word "designator" refers to something that designates, such as a label, identifier, or pointer.

English 'designator' is a broad term. In Japanese, you must choose a word based on what is being designated (a name, a target, a variable) and the context (technical, formal, everyday). Using a generic translation like 指定子 in non-technical contexts may sound unnatural.
If you're unsure which word to use, it's often safer to describe what the designator does. For example, instead of 'designator', say 'the name used for this' (このために使われる名前) or 'the symbol that indicates this' (これを示す記号).
出口の標識に従ってください。
