Problem with keyboard shortcuts - multilanguage

[deartify]

Hello
I have problem with keyboard shortcut. When I'm pressing right Alt+"z" which inserts polish sign "ż" it works as undo.
How can I disable this shortcut?

Btw thx for this great tool

Update:
I have found solution. Unicode 90 for me is "Z" and 89 is "Y". When i change this to 121 "y" and 122 "z" everything works.
around 6445 in content-tools.js
case 'windows': if (ev.keyCode === 121 && ev.ctrlKey) { redo = true; } if (ev.keyCode === 122 && ev.ctrlKey) { undo = true; }

@deartify thanks for the update - I guess we should really make these key combos configurable so that they can be easily updated for different language requirements.
