   Thanks for the request, and for linking the exact code! You'd like the Subagents picker's show active / show inactive toggle (composer.subagent.toggle-activity, currently hardcoded to ctrl+a) to be a configurable keybind in cli.json. Ctrl+A would stay the default, the footer would show the configured key, and binding it to Tab wouldn't affect autocomplete outside the picker.

   I checked the current code: the action still has an inline bind and isn't in the keybind definitions, while the other composer.subagent.* actions are. A plugin can't work around this, because the bind is hardcoded in the TUI. Maintainers will consider it.

   Adding some context on why this matters: I run OpenCode inside tmux/screen, where the default prefix is ctrl+a (or ctrl+b). The multiplexer intercepts the key before it reaches the TUI, so the hardcoded composer.subagent.toggle-activity bind is effectively unreachable unless I use the send-prefix workaround (ctrl+a ctrl+a in tmux, ctrl+a a in screen).

   Being able to remap this through cli.json would solve it without changing the default.

   Since the footer already reads shortcuts.get("composer.subagent.toggle-activity"), it looks like registering this id in config/keybind.ts (default ctrl+a) and using the resolved binding in subagents-tab.tsx instead of the inline bind: "ctrl+a" would be enough, with the footer hint following the configured key automatically.
