File uses press & hold macros to put two commands on one hard button, to make up for the missing chapter skip buttons, and others. FF becomes forward skip if you hold it for more than 0.2 seconds, RR-rear skip, play-1 minute jump (if 30 second skip is enabled on the TiVo), pause-slomo, stop is 8 second intant replay if pressed normally, or record if held for 0.2 seconds.
