That sounds like a helpful tutorial of one of the most important Krita knowledges -and- the perfect way to plug my free Rakurri Shortcut and Navigation Set for Krita to more people hahaha
I might consider it as a “how to change navigation” in Krita, or maybe mention it in the video I plan on “how to colour pick on only the selected layer” where it’s added in the Canvas Input Settings! Thank you for the suggestion.
I don’t think I have ever used Ctrl + Alt + N and I can’t find it, maybe I have unmapped it? Haha and yeah, I can feel the pianist feeling with some shortcuts. There are some shortcuts in Krita that I find hard - the most prominent example is [ and ] for brush size, which is particularly hard for me to reach as they don’t exists on Norwegian keyboards 
(I set them to A and S)
