Pop up menus
Worker uses pop up menus to access context menus of file type actions, labels assigned to files, and to access the main menu. These menus can be opened with the mouse or the keyboard and support both navigation with mouse and keyboard as well.
The menus also support on-the-fly filtering by entering some characters. Only the matching entries can be selected, the others are grayed out. This makes access with the keyboard easier. To reset a filter, just press Backspace and the menu will be unfiltered again.
