 chrome store and the one I found doesn't seem to work - it installs, but nothing happens when you use the keyboard shortcuts.
Do you know of any other solutions or workarounds?

A:

The extension works for me only if the address bar isn't focused in Chrome.
Additionally, I had to perform some manual tweaking of system shortcuts.
It seems that these keyboard shortcuts are also assigned by default to virtual desktops that don't exist at the time of you pressing the shortcut.
So you need to first add a ton of additional desktops to Mission Control, then unassign their CtrlNumber shortcuts, and then (optionally) remove those desktops from Mission Control again.
This is what I did, and starting then, Ctrl1 to Ctrl6 worked for me.

 Q:

What is the FPD bit on the PDP-10?

When an interrupt happens on a PDP-10 right, as on many other architectures you get the program counter pushed onto the stack. Actually, the program counter includes many status bits in the upper half of the word, similar to early ARMs. 
Well one of these bits is the "First Part Done" bit, which apparently may be set to 1 or 0 depending on if something was done or not. 
My question is about that bit. What is the First Part of executing an instruction? Why service an interrupt after that thing, instead of after the entire instruction?

A:

The First Part Done bit is used to signal whether a specific part of an instruction (the "first part") is done already or not. 
It is only set on instructions like ILDB ("Increment and load byte") and ILDW ("Increment and load word") that address a pointer to a byte/word in memory, increment that pointer, and then fetch the byte or word that is referenced by that pointer into a register.
My guess is the FPD bit simply signals whether the increment has been done yet or not, as the interrupt might occur before or after the increment has been done (this seems to be a sort of "non-atomic" machine instruction).
Outside the CPU itself (for example for a program) this bit has no use whatsoever according to the manuals. It simply tells the processor where to pick up after a return from the interrupt.

IIRC, this was set during very CISC-
