+<p>A markable list is a selection list with the added marking feature. The
+user can mark any number of items on the list while browsing it, and then
+execute a single command, which is applied to all the marked items. This is
+analogous to the multiple-item highlight feature used in computer GUIs.</p>
+<p>The marking feature is typically applied to lists the user manages, containing
+a large number of items that may be for example sent, moved, or deleted. By
+marking items first and then selecting a command, the user can perform certain
+operations more quickly and with less key presses than by performing the command
+separately for each of the items.</p>
+<p>Marked items are indicated graphically.</p>

+<p>The <b>Mark</b> and <b>Unmark</b> functions are available in the Options
+menu of the markable list. Alternatively, or as a shortcut, the user can keep
+the Hash (#) key pressed while using the Arrow keys and the Selection key
+in the following way:</p>
+<ul>
+<li><p>Pressing the Hash (#) key marks the current item. This is a toggling
+function, so pressing the Hash (#) key on a marked item unmarks the item. </p></li>
+<li><p>Pressing an Arrow key (up or down) while holding down the Hash (#)
+key marks both the current item and the one onto which the focus moves. If
+the user keeps holding the Hash (#) key and scrolls further in the same direction,
+all the scrolled items become marked; to unmark the items in reverse order
+the user can scroll into the opposite direction while holding the Hash (#)
+key down. </p></li>
+<li><p>Items can be unmarked by pressing the Hash (#) key together with scrolling:
+if the user starts holding the Hash (#) key down when on a marked item and
+then scrolls, all the scrolled items become unmarked. </p></li>
+<li><p>Several marking actions can be done subsequently. The user can mark
+an item, then release the Hash (#) key, browse and move the focus onto some
+other item on the list, and then mark that item. The first item remains marked,
+and the ones between the two do not become marked. </p></li>
+<li><p>All items become unmarked when the user exits the list, for example
+by back stepping. There may be exceptions to this rule in certain applications
+that require selecting items from several levels of folder hierarchy. An example
+of this is creating a play list in the Media Player application. Items remain
+marked if the user opens and cancels the <b>Options</b> menu, or swaps applications. </p></li>
+<li><p>Pressing the Selection key when there are marked items on the list
+opens the context sensitive <b>Options</b> menu containing only those functions
+that apply to multiple items.</p></li>
+</ul>
+<p>A markable list functions exactly like a normal selection list, except
+for the marking feature.</p>
+<p>Devices that have the optional Edit key perform these same functions by
+using the Edit key and arrow keys instead of the Hash (#) key.</p>
+<p>The user may access the <b>Options</b> menu to perform functions on all
+marked items at once. When user has one or more items marked, <b>Options</b> menu
+does not contain items that apply to one item only (such as <b>Open</b>).
+Exceptions are Help and Exit, which should appear in every <b>Options</b> menu.
+Appropriate error handling must be designed for functions that do not apply
+to some or all of the marked items.</p>
+<ul>
+<li><p>When executing a function, if any of the items are marked, all the
+marked items are affected by the function. If the focus is on an item that
+is not marked, the function does not affect that item. </p></li>
+<li><p>After the selected function is successfully done, all items are unmarked.
+In an error case, when the function cannot be applied, the marks should remain
+in place.</p></li>
+</ul>
+<p>The Options menu includes the marking and unmarking functions in a submenu
+so that any user can find the feature. The submenu has also the <b>Mark all</b> and <b>Unmark</b> all
+options.</p>
