I just found something this week that I didn’t know existed! I’ve been struggling having a keyboard basically for each language I study. I get it for Russian, Japanese and Farsi, but I’m finding it annoying for Italian or my native Finnish that I have to switch the keyboard to be able to write all the characters.
I found a solution!!!
Windows (I use Windows 10, but I’m sure it exists for Windows in general), there is something called US international keyboard. You can install it from your language settings (where you add languages and keyboards in general. Suddenly I can write all latin scripts with the same keyboard!
Download layout and instructions of use here.
If you need more instructions on how to install it, comment and I’ll explain more!
