Yeah, mice weren’t really a thing on the early IBM AT’s and clones when CUA was being developed. Mice were around and the GUI was very rudimentary (Windows 2.0)

Yeah, mice weren’t really a thing on the early IBM AT’s and clones when CUA was being developed. Mice were around and the GUI was very rudimentary (Windows 2.0), certainly when compared to System 4 and 5. In an ideal world, the Meta key, like those found on Sun keyboard, would have been brought over to AT keyboards to cover this.
