Oliver 2026-10-23: "ich möchte überall mit ctrl + enter senden können". Today only the chat composer says Ctrl+Enter sends. Make Ctrl+Enter (and Cmd+Enter on macOS) submit every form with a textarea: inbox answers, project message, ticker post, card create/edit, notes, member briefing, group chat, request ask, settings with text. One shared helper in dom.js, not per view; hint the shortcut in the label as the chat does; never submit on plain Enter in a textarea; respect a disabled submit button (no double send). Smoke case per form. Small card: after tsk-x995qwddkrk2.
