Shift+Tab arrives from every frontend as ISO_Left_Tab (0xfe20), which has no Unicode value and lies outside the function keysym range, so ipckeysym gave key 0 and the documented Shift-Tab wrap through search results never reached the engine; GTK moved focus instead. KP_Enter and KP_Tab likewise became unknown special keys, so the keypad Enter committed the reading and passed a newline instead of taking the highlighted candidate.
