(G)Vim and scrolling of spelling suggections

Question

When getting spelling suggestions in gvim (z= on a word) the list of suggestions is created rather slowly, I can actually see it scroll up one line at time.

When using vim in a terminal the full list seems to be generated instantly and there is no visible scrolling like in gvim.

I've tried setting ttyfast, but it has no visible effect in either gvim or vim (gvim scrolls whether it's set or not, vim never scrolls whether it's set or not).

Is it possible to get gvim to produce spelling suggestions more quickly and get rid of the scrolling effect?

Answer 1

Have a look at the 'spellsuggest' option. This has a few settings that may speed things up for you, such as 'fast' (which may be less accurate) or {number}, which limits the number of matches. If you have a large (e.g. maximised) window, you may find that it's searching for a long time. With {number}, it'll limit the matches and speed up the display.

" Look for best result, but limit results to 10 matches
:set spellsuggest=best,10
" Go for speed (at the expense of accuracy) and limit to 20 matches
:set spellsuggest=fast,20

Put whichever you choose in your vimrc. For more information, see:

:help 'spellsuggest'

:set spellsuggest?
