Thank you so much Niels! 🙂
Yes, I’ve already tried holding D and E. They’re actually handy and convenient too, and I also like this feature. Only that having shortcuts just to change the sizes (larger/smaller) without changing the slider settings would also be great to speed up the workflow. In my case, most of the time, when drawing/animating on a software, I just set the settings first according to my preference, then after that just go straight to drawing/animating and while at it, more often I just want to change the sizes of my drawing tools.
P.S. Sorry Niels, I misspelled your name in my first post.
