Canon Cat with additional sublegends

I'm taking the opportunity to do some (gentle) retrobrighting of my Canon Cat, using the vapor method. This includes the double-shot keycaps, which exhibit a bit of yellowing on the white legends.

This particular Cat has, since before I acquired it, sported additional stickers on four of the keys that add legends to the front: R, Y, H and M. They are printed on trapezoidal-shaped stickers, to match the front profiles of most keycaps. The printing is a shiny blue -- almost iridescent -- on the transparent sticker.

The legends are:

R: ENTRY MM [now lost]
Y: PITCH
H: AUTO DIAL
M: PRINT MM

Here are three of them removed from the keys, with metal stabilizers for scale:

Here's what's odd: third-party software for the Cat is, as far as I know, non-existent. (At least until @ClassicHasClass recently! ) The only reasons I can think of for aftermarket sublegends would be:

1) A hitherto-unknown piece of proprietary software (written in Lisp?)
2) Use of a mainframe, unix, or other terminal-based program over either a modem or a serial connection, as the Cat is a perfectly cromulent terminal and has an inbuilt modem.

Assuming these legends are for reason #2, what could they refer to? AUTO DIAL does in fact suggest a modem scenario -- but I don't think the Cat OS would intercept this. The Cat would like you to highlight a number and press the PHONE key, which is USE FRONT + ', of course :).

PITCH, ENTRY MM and PRINT MM could well refer to some kind of early layout/DTP program. They could relate to letter spacing and sizing. Latex or something more obscure?

Anyway, given the Cat's rarity, I thought a variation such as this (even if aftermarket and user-applied) could be worthwhile to document.

Very interesting (I assume you meant Forth, though). I've never seen nor heard of this. They are clearly aftermarket.

My best guess is the software had to run locally, since I don't think USE FRONT combinations get transmitted.

Hah, yes, Forth! :)

Are you ready for something weird? Here's another Cat with the same aftermarket labels:

This one also has a "F" legend, which probably fell off of mine.

(I considered the possibility that this might have been my Cat before I bought it, but the video dates from November 2024 and I bought my Cat in 2013. The case and keyboard aren't yellowed like mine are, and it's missing the label of a business office supply company that mine has.)

Once I figure out how to rip a YouTube Short, I can isolate the frames that show the keyboard.
