Can I use the keyboard to access shelves and launch shelf items?
Yes. You can associate a hot key to each shelf by right clicking on a tab and opening the Shelf Properties dialog. Even if you are in another application, using this hot key combination will un-collapse WorkShelf, bring it to the foreground and open the associated shelf. You can also assign hot keys to items in Regular Shelves by right clicking on the item and selecting Properties (NOT File Properties) to open the Properties Editor dialog. Note that using an item-associated hot key will launch the application silently, i.e.; without un-collapsing, opening or otherwise bringing WorkShelf to the front.
