In a working setup with your current terminal configuration, this should give either of the following outputs: t_kl ^[O*D You can check this with the following command: :set ? It's more likely that the problem is that Vim doesn't recognise the escape sequence sent, and so is interpreting it as keystrokes. However, given your setup, this is pretty unlikely to be the issue. This is described in :help vt100-cursor-keys and further in :help timeout - the suggested solution is to set a sufficiently large ttimeoutlen, but disabling timeouts entirely by setting both notimeout and nottimeout would also work. It's possible therefore on slow terminals or very busy systems that there is sufficient delay between each character that Vim is deciding it's not an escape sequence and just interpreting the keystrokes as described above.

The only way that Vim can distinguish the escape sequence from the same three characters manually typed in is by the time that occurs between the receipt of each character. What's going wrong The escape sequence might be timing out You can confirm that this is what your terminal is sending by entering insert mode and then pressing Ctrl-V followed by the Left arrow. O: Begin a new line above the cursor and enter insert mode,.Vim is not recognising this as an escape sequence, and therefore it is treating those keystrokes as if you had typed them out yourself: This can also be notated as ^[OD, where ^[ is notation for Ctrl-[, which is another way of notating or entering the ESC character.

Update A patch has been included in Vim that makes this possible using the list option.When you press the left arrow, your terminal is sending the following escape sequence: ESC O D Update I made a plugin out of this question. If you setup a function, you can easily setup a toggle command to switch displaying special Highlighting on or off. For a complete solution, look into romainl answer, that should give you a start. For the first one, one might want to setup the highlighting using a ColorScheme autocommand (so that the concealed chars always look the same, independent of what a color scheme actually sets up). The last two items means, you would have to setup some autocommands that reset the syntax rules and the correesponding options. (I have not tested which one actually works). This could be done using a BufWinEnteror possibly also a Syntax or even FileType autocommand.

The syntax highlighting groups need to be executed whenever a syntax definition file is reloaded.

That means they can be different in different windows (and will possibly be also set by filetype plugins or other plugin scripts). The conceallevel and concealcursor are window local options.(This means, you need to built your own Vim to use this). The latest one at the time of writing seems to be this one. There seems to be a patch floating around, that will allow to customize how spaces will look in list mode.There will be no way around (perhaps this will be fixed, I posted a patch) There seems to be a particularity that Vim will not highlight spaces, if the syntax script uses the skipwhite keyword. :hi Conceal ctermfg=7 ctermbg=NONE guifg=LightGrey guibg=NONE if your syntax script conceals some more items, they will be displayed as your white space chars). But this affects all concealed chars (e.g. For highlighting, you would have to at least once configure the 'Conceal' highlighting group (See the help at :h hl-Conceal This can be done in your colorscheme and then you do not need to reconfigure it again. You can configure, how the concealed chars look. It is of course possible to define some highlighting for the conealed characters. This needs a vim 7.3 with +conceal feature Depending on your syntax rules for the current buffer, something like this could work: :syn match WhiteSpace / / containedin=ALL conceal cchar=Æ
