I believe you can do this with the on-screen keyboard! If you're using Windows, I think that can be accessed with super+u (but I haven't used Windows in a long time so I apologize if I misremembered or if this is no longer accurate).
Or better yet, start using the US-international keyboard layout. You press the accent you want (', `, ", ~, ...) and the letter you want it on, and boom. Writing normal versions of those symbols requires a space after writing them, but that's easy to get used to.
It's pretty much the default setting in the Netherlands.
I remember this from working on a DOS PC with a German keyboard. Which has no backslash character, among other characters one need for programming. Having äöü at your fingertips is no help if you need [].
Don’t you guys have dead keys? On German keyboards there’s a key that does nothing on its own. When you press it twice, you get '`', and when you press that button and 'e' you get è.
Many people confuse this for the apostrophe which brings me into a murderous rage every time I see it.
We (Canadians) actually have two layouts to type French characters. The modern Canadian multilingual layout, and the traditional "French (Canada)" layout. As an older French speaking Canadian, I prefer the traditional layout but both work. You can even type English words with these.
