Oh, I see. I had exactly that question. What do you do when you actually want a backquote or an apostrophe? something like Shift+’ ? If this is the case, then I think it’s possible to have a custom layout where pressing the apostrophe key accents the previous letter, and Shift+’ inserts an apostrophe, and the same for the backquote.
It’s more dumb than Emacs, because it doesn’t know which letters should be accented and which ones don’t, but it’s very similar.
