navigation keys to select (highlight) text, which
then enables the copy and cut functions.
- In markable lists, using Edit key together with
navigation keys allows the user to mark several
items of the list, then a function can be executed on
all the marked items as one operation.
The Edit key is handled in a special way: the primary
action (editing options menu) is opened from the
key release event, not the key down event as it
would usually be. This is to enable the mark/select
function where the key is being held down as a
modifier key.
(See sections
Editing
and
Lists and Grids
for more
detailed descriptions on the select and mark
functions.)
Power
- Turns power on and off. This requires a long key
press.
- Opens the Profiles menu for switching active
profile.
Navigation
The model of navigation is based on states arranged as hierarchical trees, familiar
from existing UI concepts. A few added features bring in new flexibility:
Tabs

·
Applications key and the Application shell
Direct navigation between sibling folders
Links to applications and documents; Pinboard
These features are described in the following sections.
Navigating in applications
The traditional hierarchical tree structure forms the basis for navigation. The user can
move forward from one node (state) by opening an available item or selecting an
option from a menu. Back function (available in the right softkey
Back
) returns to
the previous level in the hierarchy. In the initial state of an application (number 1 in
the figure below) the Exit function replaces Back in the right softkey; it closes the
application.
