pugmajere's Google Meet optimized version of the default keymap

A lightly modified version of the default keymap.

The top row is converted to keys used for muting audio and video in Google Meet, in both Linux and MacOS. (Yes, they annoyingly have different conventions.)

The ASCII-art depiction uses "C-E" to mean "ctrl-e", and "M-E" to mean CMD(GUI) and "e", roughly following Emacs naming conventions.
