| 3 | // Regression coverage for transcript selection actions. Selected message text |
| 4 | // exposes Add to Chat after pointer/keyboard selection, while the Wails shell |
| 5 | // also keeps its app-drawn right-click Copy menu: |
| 6 | // - a non-collapsed selection inside .msg__body opens the menu and Copy |
| 7 | // writes the selection through the runtime clipboard bridge |
| 8 | // - collapsed selections, non-message selections, editable targets, and |
| 9 | // plain-browser sessions (no window.runtime) never open the menu |
| 10 | // - a surviving message selection does not hijack right-clicks landing |
| 11 | // outside message bodies (project tree, tab bar, ... own those menus) |
| 12 | // - the target message must itself touch the selection: selecting message A |
| 13 | // and right-clicking message B offers nothing (Copy would copy A), while a |
| 14 | // selection spanning both accepts a right-click on either |
| 15 | // - Escape dismisses the floating action without clearing the selection, the |
| 16 | // trailing keyup does not re-open it, and a fresh pointer gesture does |
| 17 | // - the add-to-chat shortcut lives in the shared registry: rebinding it in |
| 18 | // settings remaps both the handler and the visible hint |
