* R is the row number for the top of the display element, in pixels counting down from the top of the display, with R0 being the top row. The default is the same row as used for the previous element. The default at the start of the file is 0.
* C is the column number for the left hand edge of the display element, in pixels counting from the left, with C0 being the leftmost column. The default is one pixel after the previous element ends. The default at the start of the file is 0.
* GA is the name of a commandan action to execute, either a Gcode command or a menu commandexecute (see later)

* F is a font to select. There are currently two fonts, 0 (small, the default) and 1.
* D is a number of decimal places to show when displaying numbers. If zero (which is the default), no decimal point is shown.
* T is text to be displayed
* L is a menu or image filename to be used

An action string ('A' parameter) can be any of:
 
* A Gcode command string (must begin with G, M or T). In such a string, #0 represents the full name of the current file, in double quotes. When executing the 'files' command, this is the file selected by the user. When executing the 'button' command, this is copied from the L parameter.
* 'menu' chains to the menu file given in the L parameter
* 'return' returns to the parent menu
 
Multiple actions can be specified, separated by the vertical-bar character, e.g. "M32 #0|return|return" but 'menu' if present may only be the last command.
 
The V parameter in the 'button' command specifies the button's visibility with value:
 
* 0 always visible (default)
* 2 visible when the printer is actively printing (actively printing defined as not paused, pausing or resuming)
* 3 visible when the printer is NOT actively printing
* 4 visible when the printer is printing (includes paused, pausing and resuming states)
* 5 visible when the printer is NOT printing
* 6 visible when the printer is printing and in paused state (paused or pausing)
* 7 visible when the printer is printing and NOT in paused state (actively printing or resuming)
* 10 visible when SD card 0 is mounted
* 11 visible when SD card 0 is NOT mounted
* 20 visible when the current or default tool has a temperature fault
* 28 visible when the bed heater has a temperature fault
 
The N parameter in the "value" and "alter" commands specifies the value to display or change as follows:
 
* 000-078 Tool N first heater current temperature e.g. 0 = tool 0 current temperature (display only)
* 079 Currently selected tool first heater current temperature (display only)
* 080-089 Bed heater (N-80) current temperature e.g. 80 = bed heater 0 current temperature (display only)
* 090-099 Chamber heater (N-90) current temperature e.g. 90 = chamber heater 0 current temperature (display only)
* 100-178 Tool (N-100) first heater active temperature e.g. 100 = tool 0 active temperature
* 179 Currently selected tool first heater active temperature
* 180-189 Bed heater (N-180) active temperature e.g. 180 = bed heater 0 active temperature
* 190-199 Chamber heater (N-190) active temperature e.g. 190 = chamber heater 0 active temperature
* 200-278 Tool (N-200) first heater standby temperature e.g. 200 = tool 0 standby temperature
* 279 Currently selected tool first heater standby temperature
* 280-289 Bed heater (N-280) standby temperature e.g. 280 = bed heater 0 standby temperature
* 290-299 Chamber heater (N-290) standby temperature e.g. 290 = chamber heater 0 standby temperature
* 300-398 Fan (N-300) percent full PWM e.g. 302 = fan 2 percent
* 399 Current tool fan percent full PWM
* 400-499 Extruder (N-400) extrusion factor
* 500 Speed factor
* 510-516 Current axis location (X, Y, Z, E0, E1, E2, E3 respectively) (display only)
* 519 Z baby-step offset (display only)
* 520 Currently selected tool number
* 530-533 Actual IP address, octets 1 through 4
