The SHIFT key (while engine is moving) does nothing (both keys). I have enabled and disabled, loaded and reloaded, different routes, ets. - pressing the RETURN key while the engine is in motion does nothing. Works OK in TS-2019. Different routes, track and engines same result. For me a valuable feature. Total waste of time running at normal speed during debug. The keyboard functions as it should in several other circumstances. I had this in 2019 but there it was my fault not setting Debug Enable option.
