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.

detailed descriptions on the select and mark
functions.)
