Use the cursor keys to select a menu item.  Left-Right cursor keys select the main menu category and Up-Down cursor keys select the submenu item.  Just under the menu selections, a more detailed description of the menu item's action is displayed.
The "Current" coordinates display where the telescope is currently pointing.
The "Input" coordinates display user input coordinates, ready for the telescope to be moved to, if "Move To/Equat" or "Move To/Altaz" is selected from the menu.
The "Drift" coordinates show the current drift rate in each axis.
Encoder coordinates are displayed in degrees and in raw counts.
The "FieldRot" or field rotation shows one value if field rotation motor disabled, otherwise shows four values.  The upper value is the current field rotation angle.  The second value down is the rate of field rotation in degrees per minute.  The next value down is the angle of the field rotation motor.  The two numbers immediately below show the accumulated step count (clockwise adds, and counterclockwise subtracts), and the number of resets: all modulus 100. The final angle displayed under this line is the guide buttons rotation angle.
The "Focus" position shows the accumulated count of the focuser stepper.  If no number is displayed, then the FocusMethod is set to something other than stepper motor control
The "AirMass" field shows the airmass number, or number of atmospheres that the telescope is aimed through.
The "DomeAzimuth" field shows the angle of the dome rotation in degrees.
The "File" area indicates which data file, or external program or device, has sent coordinates to the program.
If the coordinates have been reset because the encoder reset threshold values in the config.dat file have been exceeded, the "File" field will display a message stating the scope motion immediately preceeding the reset (enc.res.slew = encoder reset after slew, enc.res.on = encoder reset after tracking on, = encoder reset after tracking off), and a running count of the encoder resets for that particular scope motion.
The "Track" field shows if tracking is on or off. 
The "TrackFRMotor" shows if the field rotation motor tracking is enabled/disabled.
The "Init" field shows how many initializations have been done so far.
The "GEMFlip" indicates if a german equatorial mount has been flipped across the meridian.
The "Object" area shows which object from the data file has been loaded into the input coordinates.
The "Handpad" field shows what handpad mode the program is currently in, and if that mode is active (for instance, if the mode is set to focus, and control of the focus motor is activated by the mode switch, then an 'on' will appear), if handpaddle auto-drift-update is on or off (DUon or DUoff), if guiding corrections saved to a file are finished then a "Fn" will appear, and further to the right, which buttons are being pressed and the switches' positions.  C=clockwise button pushed, W=counterclockwise button pushed, U=up button pushed, D=down button pushed, m=speed switch in microstep position,H=speed switch in halfstep position, L=mode switch in left position, R=mode switch in right position, x = up, down buttons reversed. 
The "Mouse" field shows the mouse mode: mouse modes include menu, where the traditional point and click is available, and various move modes, where mouse movement moves the telescope.
The "Microstep" field displays the current microstepping speed in arcseconds per second.
The "PWM" field shows the actual number of pulse width modulations per bios clock tick (there are about 18.2 clock ticks per second), and the averaged number of PWMs per timer tick that the program is currently using.
The "Ms" area shows the number of microsteps moved per timer tick (occurs 18.2 times per second) for altitude and azimuth motors, the winding from 'a' to 'd', the microstep within the winding for altitude and azimuth motors.
The "QSC" shows the current quarter step correction values for both motors.
The "Guide" field displays the current guiding speed in arcseconds per second.
The "FastFocus" displays the fast focus speed in steps per second.
The next area shows if the field rotation motor is moving "Fr+" or "Fr-", any auxiliary control lines activiated "A1" or "A14" or "A16" or "A17" and if the focus motor is moving "Ff+" (fast out) or "Ff-" (fast in) or "Fs+" (slow out) or "Fs-" (slow in).
The "SlowFocus" displays the slow focus speed in steps per second.
The "PEC" area, if PEC is on, shows the altitude and azimuth indexes and correction values in tenths of an arcsecond, respectively.  In addition, if the auto-sync of altitude PEC or azimuth PEC is enabled, the PEC index at synch point is shown, and if an error, the PEC display is highlighted with the current selection color.
The "AZEC" shows the altitude vs azimuth error corrections in arcminutes.
The "AAEC" shows the altitude vs altitude error corrections in arcminutes.
The "ZZEC" shows the azimuth vs azimuth error corrections in arcminutes.
The "PMC" shows the pointing model error corrections for altitude and azimuth in arcminutes.

If using interrupt method to time the half steps, the "Slew" field will display the slew status, slew abort reason, the ramp half steps (1/2 of the total steps to move), the ramp up steps (steps taken while ramping up to max speed), the steps taken while at maximum speed up to the midpoint of the move, the remainder of the steps taken at maximum speed, the ramp down steps, and the current speed index (larger numbers = slow speeds, smaller numbers = high speeds).

If the menu option to display LX200 is turned on, then the LX200 field will show the history of commands received with an '*' by the last command, and, the next line down will display the raw characters as received from the external device ouputting the lx200 protocol serial data.

Coordinates' display on the screen:

There are three main coordinates displayed: encoders, current, and input. The current coordinates show the scope's current position. The encoders coordinates show the positioning as relayed from the encoders. The input fields show coordinates that will be used if any of the move or reset to input menu items are selected.  Inputting new equatorial coordinates does not change whatever inputted altazimuth coordinates are present, and visa versa.

Shortcut keys:

'1' selects 'move to equat'
'2' selects 'track on/off'
'3' saves current equatorial coordinates
'4' retrieve saved equatorial coordinates into the input fields
'5' saves current #2 equatorial coordinates
'6' retrieves saved #2 equatorial coordinates into the input fields

'c' displays PEC graphically
'd' selects 'data file' menu item
'e' averages PEC analysis files and displays results graphically for the altitude axis
'f' averages PEC analysis files and displays results graphically for the azimuth axis
'g' selects menu item 'Guide.bat' (which calls Wguide.exe, passing it the current scope coordinates, the DOS 32 bit version of Guide)
'h' selects menu item hand paddle, toggling through handpad modes
'H' selects a hand paddle mode from a selection palette
'i' displays the initializations
'k' kills the inits
