macOS browsers swallow C-a above xterm.js (the launcher intercepts nothing — the keystroke never arrives), so C-a C-a and C-b C-a are both undeliverable and no app can receive a real Ctrl-a from a Mac.

That app is herdr in the herd channel: its prefix is ctrl+a to match the ssh front door, and herdr accepts a single prefix, so the browser cannot have its own.

C-g was unbound and passes through the browser cleanly, so bind it prefix-free to send-keys C-a — one keystroke instead of a chord. Added to the sidebar cheat sheet.

Cost: in claude channels C-g now means beginning-of-line rather than readline abort.

macOS browsers swallow `C-a` above xterm.js (the launcher intercepts nothing — the keystroke never arrives), so `C-a C-a` and `C-b C-a` are both undeliverable and no app can receive a real `Ctrl-a` from a Mac.

macOS browsers swallow C-a above xterm.js — the launcher intercepts
nothing, the keystroke just never arrives — so neither `C-a C-a` nor
`C-b C-a` can deliver one, and any app that wants a real C-a is
unreachable from a Mac.

That app is herdr in the `herd` channel. Its prefix is C-a so it matches
the ssh front door, and herdr takes a single prefix, so the browser can't
have its own. C-g was unbound here and passes through the browser fine,
so bind it (no prefix) to send-keys C-a: one keystroke, not a chord.

The cost lands on the `claude` channels, where C-g now means
beginning-of-line instead of readline's abort.
