note: Tmux 70/20/10 Layout Shortcuts

Published Tmux 70/20/10 Layout Shortcuts, a note about building a one-keystroke tmux layout that creates a stable 70/20/10 vertical stack and only allows pane swapping when the window is explicitly tagged as that layout. The useful part was not just the final run-shell binding, but the testing approach: using detached tmux sessions plus list-keys, list-panes, and show-options as a lightweight TDD harness before touching the real config. This is one piece of a broader terminal and editor workflow cleanup, and I want to write that larger tmux plus lightweight Emacs story up properly soon.
