A few of the shortcuts are not performing as expected. For example, the shift shortcut does work to enable “Add Selection Mode”; however, alt does show “Remove Selection Mode” in the center of the screen however it does not remove anything from selection when clicking. Also the Undo & Redo Shortcuts do not work. The shortcut guide, which appears when cmd+shift is pressed also shows a copy command which does not work. And, finally, the delete shortcut is option delete on keyboards that do not have a backspace. This is not a big deal, but if you create a shortcut guide like in the App Store it should probably list both options. I will say, though, I really love the shortcuts and find them very useful. The shortcut guide is also a very nice feature to have in case you forget one or two shortcuts, something I really wish programs like Blender had.
