You devs could make shortcuts more practice, just adding the left click mouse button over the icon and add the function "atribute shortcut" just like in blender, it would make a million more easy to use that software.
Hello! You've reached the KDE bug tracker, which is for tracking and investigating specific bugs. Unfortunately there is not enough information in here to proceed or pinpoint where a bug (if any) in KDE code might be. Can you please read https://community.kde.org/Get_Involved/Issue_Reporting and add more information here, including why you think it might be a bug in any KDE software? If you read through that wiki page and don't feel like it's helped at all, I'd recommend posting a question at https://discuss.kde.org/c/help/6, and hopefully the people there can help you. Thanks!
