I don't know if "quick to type" has ever been a reason?
Short words mattered in the early days, with punch cards, very limited memory and computing power, shorter words saved resources. Also, when running a program means handing a stack of punch cards to an operator and waiting for the result to come out the next day, saving a few seconds of typing probably wasn't a priority.
As computer got fast enough not to care about single bytes, there was a push against using shorter names. "be descriptive" they said. Also we had more advanced editors with copy-paste, search and replace, etc... If there was an objection for overly long variables, it was more about screen real estate than typing speed.
I'd say the case where it mattered would be interactive shells, UNIX shells in particular, because for DOS, commands were limited to 8 characters by the filesystem, another technical limitation. But then came completion, making typing speed not really an issue, but you still want to be able to fit your command in one line, because otherwise it is annoying.
So: technical limitation or readability rather than typing speed.
