Touch one of the available commands to select it. (Or, touch anywhere else 
on the screen to make it disappear, with no command selected).
Pop-up menus
When a down-pointing arrow appears next to a parameter name, touch the 
arrow to open the pop-up menu and choose an option from there (by touch-
ing the option, or scrolling the list with the VALUE control). As an alternative, 
touch the parameter name and use the VALUE control to scroll the list of 
options.
If you want to make the menu disappear without selecting anything, touch 
anywhere else on the display.
Lists and scrollbars
Files on storage media, as well as other kinds of data, are shown as lists. Use 
the scrollbar to scroll the list content. Also, you can use the VALUE control 
to scroll.
