M8 Headless Cheat Sheet

The above image is borrowed from the manual for the M8 Operation Manual. This shows the layout for the physical M8 Tracker device. The text in gray on the eight buttons on the bottom half of the device is what I’ve added to the provided image. Here is a more useful detail:

Those eight keys are, I believe, the default settings for using a computer keyboard as replacements for the physical buttons on the official M8 Tracker. From my experience with the M8 Tracker, you cradle it with both hands and control the buttons with your thumbs, though I imagine some people may rest the device on a table, or lap, and employ additional fingers.

This is a picture of the first version of the M8, which is the one I have. There’s a more recent version, but the buttons are in the same place.

I’m trying to port some of my experience with the official device to running the software on a Teensy 4.1, connected to my laptop with a USB cable, as I’ve mentioned here recently. The transposition gets a little confusing, in part because I’m inclined to use more than just my thumbs on my laptop, and also because the arrow keys are on the lower right side of my laptop keyboard but on the upper left side of the M8 Tracker. Much M8 use is muscle memory.

I’ll continue to track, so to speak, as I explore the M8 Tracker further.
