Yes, i know this backstory which is why i mentioned radio buttons: they called like that because of some historical reference, not because they have anything to do with radios.

Similarly comboboxes are called like that because of historical reference (to the combobox control on Win32 that provided the functionality) even though they aren't really a combination of input box and list.

(though one could claim that they are still a combination of a button and a drop-down list, so the name still has some relevance to what is displayed, unlike radio buttons)
