Keyboard Selection from Menus. Every Tornado menu has a one-letter
abbreviation, shown by underlining that letter in the menu bar. Press the
META shift and that letter to display the menu from the keyboard rather than
using the mouse. While the menu is displayed, you can dismiss it without
selecting a command by repeating the same META-letter shortcut.
Within a menu, there are two ways of selecting and executing a command from
the keyboard. Each command name also has an underlined letter; press that
letter (no META shift at this level) to execute the command immediately. For
example, the key sequence META-F Q selects Quit from any File menu. You can
also use the arrow keys on your keyboard to highlight each successive menu
command in turn; press RETURN (or ENTER) to execute the currently
highlighted command.
Keyboard Operation of Forms (Dialogs). When a form is displayed, the TAB
key selects each text or scrolling-list field in turn (shift-TAB selects them in
reverse order). Type directly in a text field to change its value; in scrolling lists,
select a new value with the arrow keys.
When no scrolling list is selected, the arrow keys select in turn each of the
toggles or buttons on the form; RETURN (ENTER) switches the highlighted
toggle or presses the highlighted button.
Left Mouse Selects, Middle Mouse Drags. When there is selectable text in a
Tornado display, use the left mouse button to select it. For objects that can be
dragged, use the middle mouse button.
Folder Hierarchies. Whenever hierarchical data is presented graphically, a
folder icon appears at each level of the hierarchy. Click on these folders to hide
subordinate information; click again on the folder to reveal it once again.
