Keyboard shortcuts work best when you access the application from the dedicated account created when you installed Smoke. In this case, the Autodesk dlu keyboard is selected by default. If you start Smoke from a different account, you may notice some keyboard shortcut irregularities.
In the Keyboard Shortcut Editor you can also select the type of keyboard you are using to take advantage of extra keys on certain keyboards.
When you select your keyboard, the onscreen keyboard is changed to reflect your choice, and entries in the Keyboard Shortcut Catalogue are updated accordingly.
