When the TNC is on, the selected operating modes are shown
in the screen header: the machining mode at the left and the
programming mode at right. The currently active operating
mode is displayed in the larger box, where the dialog prompts
and TNC messages also appear (unless the TNC is showing
only graphics).

key row. You can select these functions by pressing the keys

Setting the screen layout
You select the screen layout yourself: In the Programming
mode of operation, for example, you can have the TNC show
program blocks in the left window while the right window displays
programming graphics. You could also display the program
structure in the right window instead, or display only program
blocks in one large window. The available screen windows depend
on the selected operating mode.
To change the screen layout:
Press the screen layout key: The soft-key row
shows the available layout options, see "Operating
modes", page 62
