Fn
The <Fn> switch provides access to up to 14 special functions, some of
which are pre-defined, such as <DX LIST>. F1 through F8 can execute
user-defined command sequences or macros; see MACRO
PROGRAMMING.
The following special functions are available. Other special functions
will be added as they become available.
SCRN CAP (F9)
Tap <Fn>, then <SCRN CAP> to capture the content of both the LCD
and external monitor into two separate files. You'll need to have a USB
flash drive installed in one of the three USB A jacks. Also see
MENU:Screen Cap File. Note: There is no "eject" control for the flash
drive, as required on some computers. The K4 mounts/unmounts the
flash drive (from a software perspective) as needed.
MACROS (F10)
Tap <Fn>, then <MACROS> to enter the macro editor. This can be used
to create user-defined macros for Fn > F1 through F8. Also see MACRO
PROGRAMMING.
SW LIST (F11)
Tap <Fn>, then <SW LIST> to see a list of all software components and
their currently installed revisions. At the top of the screen, in
parentheses, is the overall release number (e.g., R22).
UPDATE (F12)
Tap <Fn>, then hold <UPDATE> to go to the K4 software update
screen. Tap the <?> button for detailed instructions on how to update
software or restore an earlier version. An ethernet connection is
generally required for this purpose, though it's also possible to load
