The /vast/ majority of vim users (at least, if #vim on Freenode is anything to go by) would find that more intuitive and correct; most aren't even aware of the Tab == C-i identity anyway. Those few people who do rely on C-i actually meaning the same as Tab will know enough to double-map them anyway. > Most new users to vim are > also new to terminals, and therefore they (like me) won't know that > pressing <tab> is the same as pressing <c-i>.

Hell, if all else fails, you can just copy-paste my libtermkey sources directly into the vim tree - I specifically allow that sort of thing by it having the MIT licence. In case that isn't sufficient I will specifically state that now: I will allow you to copy the libtermkey sources into vim, alter or modify them, and use them in any way you see fit in order to make this feature work. Initial research on a new blank vim looks promising. While it won't recognise the keys you press, it does at least allow storing of 'map's for them: <C-S-i> "Again" <C-i> "World" <Tab> "Hello" <C-m> "Again" <C-j> "World" <Enter> "Hello" Curiously, while it can handle é vs <M-C> and <A-C>, it does seem to consider M- and A- distinct: <M-C> "World" <A-C> "Hello" é "Again" -- Paul "LeoNerd" Evans [email protected] ICQ# 4135350 | Registered Linux# 179460 http://www.leonerd.org.uk/
