+
+### 0..21
+
+Switches 0 to 21 control bits 0 to 21 of the SWITCH register.  The UP position represents a 1, and the DOWN position
+represents a 0.   Once all the bits have been set, you can choose to load the contents of the SWITCH register into the
+ADDRESS register (as displayed by the top row of LEDs), or directly into the memory location referenced by the ADDRESS
+register (where it will become the DATA displayed by the second row of LEDs).
+
+The SWITCH, ADDRESS, and DATA (aka DISPLAY) registers are all internal to the Front Panel hardware, and should not be
+confused with CPU registers.
+
+### TEST
+
+This is a momentary switch that is normally in the DOWN position.  When held in the UP position, it turns on all LEDs.
+This "lamp test" was more important in the days when the lights were produced by bulbs with filaments that could burn out,
+and if you didn't realize that a particular light was "burned out", you could mistake it for a zero.
+
+While the TEST switch is more "cute" than useful on a virtual Front Panel, we have added one "innovation" to the switch:
+pressing it also returns all the SWITCH register switches (0-21) to their DOWN position.
+
+### LOAD [ADRS]
+
+This is a momentary switch that is normally in the UP position.  When pressed DOWN, it copies the SWITCH register to the
+ADDRESS register.
+
+### EXAM
+
+This is a momentary switch that is normally in the UP position.  When pressed DOWN, it reads the memory location referenced
+by the ADDRESS register and displays it in the DATA register.  If pressed repeatedly, each repetition also automatically
+adds 2 to the ADDRESS register, making it easier to examine a series of words.  Note that if the CPU registers are being
+examined (starting at address 177700), the ADDRESS register will advance by 1 instead of 2.
+
+Another "innovation" unique to PDPjs: if the STEP switch is toggled from the UP to the DOWN position, repeated EXAM or DEP
+operations will decrease the ADDRESS register instead of increasing it.
+
+### DEP
+
+This is a momentary switch that is normally in the DOWN position.  When pressed UP, it writes the contents of the SWITCH
+register to the memory location referenced by the ADDRESS register, and displays the result in the DATA register.  Like the
+EXAM switch, if DEP is pressed repeatedly, each repetition also automatically adds 2 to the ADDRESS register, making it easier
+to deposit the same value to a series of words.
+
+### CONT
+
+This is a momentary switch that is normally in the UP position.  When pressed DOWN, it will start the CPU if it's currently
+halted.  If the CPU is already running, CONT has no effect.  Also, if the ENABLE/HALT switch is in the DOWN (HALT) position,
+then the CPU will continue for only ONE instruction and then stop again.
+
+### ENABLE/HALT
+
+This switch is a toggle that is normally in the UP (ENABLE) position.  If it pressed DOWN while the CPU is running, the CPU will
+stop.  Once the CPU is stopped, this switch has no effect, other than determining what CONT will do when pressed.
+
+### STEP
+
+On a real PDP-11, this would select between cycle-stepping vs. instruction-stepping.  Since PDPjs doesn't support cycle-stepping,
+this switch has no effect (except as described above when the EXAM or DEP switches are pressed repeatedly).
+
+### START
+
+The START switch is similar to CONT, but it also performs the equivalent a RESET instruction before starting the CPU, so
+unless you're starting execution at the beginning of a program, using START instead of CONT to continue execution is probably
+not a good idea.  Also, if the ENABLE/HALT switch is in the DOWN (HALT) position, START will still reset the machine but not
+execute anything.
