[quote]It works for jumping from post box to post reply button. [/quote]
	It did not do that for me, for instance - it is device/browser-specific function. (Actually, if it did do it, I'd probably have been not too happy with it in here ... hitting tab while writing is so ingrained in me that I keep doing it even when tab has exactly nil effect...)
	It is also one move per post, rather than the two-three dozen for average RP post (well, that's me in advanced section, but regardless) - and I'd say it is far more taxing for someone with hand problems to go shift-tab three dozen times than once.
