#### Should keys represented with <kbd> tags be always uppercase?

In [this edit to "Delete from cursor to end of line in `vi`"](https://unix.stackexchange.com/posts/4416/revisions) `d``$` was changed into `D``$`. I thought the answer was incorrect since `d` and `D` commands are different in Vi; I had to read the edit note by AdminBee to understand the reason for the change, namely

Although it makes sense, I think it does more harm than good. I want to roll it back, but first I'd like to invite more opinions.
