Maybe this is why the candidate menu flick

[UncleBill]

I set

let g:neocomplcache_enable_auto_select = 1

But the odd selecting behavior:

1.First, I type he, and the menu pops up

2.automaticly select the 1st match

3.then, "head" becomes "he" again ( update)

---

3 steps make it flick

[Shougo]

3.then, release it,

What's the release? Please tell me the keymappings in detail.

I think you should map to <C-e> and <C-y>.

inoremap <expr><C-y>  pumvisible() ? neocomplete#close_popup() :  "\<C-r>\""

inoremap <expr><C-e>  pumvisible() ? neocomplete#cancel_popup() : "\<End>"

[UncleBill]

What's the release?

"head" turn back "he"

[UncleBill]

I re-edited it

[UncleBill]

I think you should map to and .

I tried that, it still flicks. problem is:

1. I type "he"
2. ["head","heart","heat".etc] poped up
3. "head" is automaticly select, "head", the whole word appended to file
4. soonly, "head" becomes "he", automaticly

OK. This is Vim's feature. Because, neocomplcache/neocomplete.vim uses keymappings hacks. Like this:

  return  !pumvisible() ? "" :
        \ g:neocomplete#enable_auto_select ? "\<C-p>\<Down>" :
        \ "\<C-p>"

If neocomplcache/neocomplete.vim opens popup menu, the first candidate is automatically selected. But it is not intended behavior for auto completion. So auto completion plugins uses the hack like "". But if your Vim is too slow, it flicks. It is Vim's feature. I cannot fix it.

But I and Nayuri Aohime developped this patch. https://groups.google.com/forum/?hl=ja&fromgroups#!topic/vim_dev/tVsk0pdOGvs if you apply this patch, this behavior is fixed in neocomplete.vim. So, you may support this patch in vim_dev. Because, Mr.Bram does not responce to it...
