Add ctrl+y shortcut for redo

[ctmbl]

Hi @dullage, thanks a lot for creating and maintaining flatnotes, I really love the simplicity/usability/UX of the project!

I was wondering if you already considered adding a redo feature (as opposed to undo / ctrl+z)?
I really don't know if it is easy or even feasible but it would be a nice feature imo, from my personal experience ctrl+y is a rather classical shortcut for such feature.

Let me know what you think of this 😉

Hey @ctmbl. Testing this in Firefox on my Mac and CTRL+Y works as expected. But in Firefox on my Windows machine, it doesn't.

To be honest, I'm not sure if the editor component is responsible for this task or the browser.

But what I did find is that the editor component supports a redo shortcut of CTRL+SHIFT+Z.

I hope this helps.

Nor do I 😕

This is good enough then!
Because it is not an easy shortcut to be find, would you consider adding it to the wiki, maybe with a precision saying that it isn't a feature of flatnotes strictly speaking?
EDIT: On second thought, and after googling for ctrl+shift+z it seems like both this one and ctrl+y are pretty standard redo shortcut 😅 I just never had heard of the former for some reason 😕

Also (even if I got that it was a Toast UI bug, and that the issue is closed) it kind of provide a solution to #271

In any case tks a lot! Feel free to close this one if you want to 🙂
