I typed z= underneath a misspelled word, and vim split the screen horizontally, thereby keeping the misspelled word in context, but also providing a list words to change the misspelled word from. Usually, this latter screen replaces the former screen when I hit z=.
I like this behavior, but can not replicate it. I must have hit something before z= but I do not know what.
The behavior you saw accidentally happens when there are only a few suggestions and they don't fill the entire window.
You can force a maximum size for the suggestion list (example: 20 suggestions) with
set spellsuggest=best,20
Now, as long as your window exceeds 20 lines, you will see the misspelled word in context, and the bottom 20 lines of your window filled with the suggestion list
I can't say what caused the behavior you saw, maybe it is some plugin.
But here are two options to stay in the context with spellchecker:
1) Use CTRL-X s in insert mode:
In Insert mode, when the cursor is after a badly spelled word, you can use
CTRL-X s to find suggestions. This works like Insert mode completion. Use
CTRL-N to use the next suggestion, CTRL-P to go back. |i_CTRL-X_s|
2) Use vimple plugin which turns few full-screen windows (including spell suggestions) into "overlays" (actually split windows where you can select the word you need).

In Neovim, with the spell checker enabled by set spell, if you hover over a word which is underlined to indicate improper spelling and type z= a window will open which obscures the entirety of your work to list all of the suggested words. I would like for this window to be split horizontally, above, or below the the current buffer so that I can select the properly spelled word while still being able to see my work.
I'm not sure if this is possible. I can't find a setting that would change this functionality.
While not an exact answer to your question, you can just make a remap to display a drop-down list of suggestions like so (see image below - just Tab to traverse the list and press <Esc> to choose and be returned to normal mode):
" move to insert mode with drop-down menu of spelling suggestions for word under the cursor
nnoremap <Leader>sp a<C-X>s
I found that 99% of the time I chose the first spelling suggestion, so I made the mapping to do that and return to normal mode - with no window/drop-down list appearing - hence all you see is the word instantly change.:
" instantly go with first spelling suggestion for word under the cursor
nnoremap <Leader>sp a<C-X>s<Esc>
N.B. The above remaps work better than:
nnoremap <Leader>sp z=1<cr><cr>
since with this one there's a brief flash as the suggestion window appears and is quickly closed again.
Yes, there is an options called spellsuggest. You can use the following setting:
" use only 9 suggestions
set spellsuggest=best,9
After that, the spell suggestion will take only a small portion of the window:
I am trying to use the vim autowrap functionality to automatically wrap my paragraph into lines no longer than 80 letters in real time as I type. This can be done by set textwidth=80 and set fo+=a. The a option of the vim formatoptions or fo basically tells vim to wrap the entire paragraph while typing.
However, there is a very annoying side-effect, that I can no longer break a line by simply pressing enter.
This is a sample sentence.
Say for the above sentence, if I want to make it into:
This is
a sample sentence.
Usually I can just move the cursor to "a" and enter insert mode and then press enter. But after set fo+=a, nothing will happen when I press enter in the insert mode at "a". One thing I do notice is that if there is no space between "is" and "a", pressing enter will insert a space. But nothing else will happen after that.
So what do I miss here? How do I stop this annoying behavior?
You can run :help fo-table to see explanations of the options:
a Automatic formatting of paragraphs. Every time text is inserted or
deleted the paragraph will be reformatted. See |auto-format|.
When the 'c' flag is present this only happens for recognized
comments.
This means that every time you insert a character, vim will try and autoformat the paragraph. This will cause it to move everything back onto the same line.
I don't think you need to add a at all. I use neovim, but the behavior here should be the same. The default values are, according to the help pages:
(default: "tcqj", Vi default: "vt")
Try removing set fo+=a entirely from your .vimrc. Keep set textwidth=80. That should fix your issue.
EDIT: Once you have set textwidth=80, if you want to format an existing paragraph, you can highlight it in visual selection and press gq.
The following allows me to use the enter key to start a new line while setting the text width to be 79 characters:
set tw=79 "width of document
set fo=cqt
set wm=0 "# margin from right window border
After some exploration, I find a workaround that can solve the problem to some extent, though not perfect.
The basic idea is that when entering a line break, disable the auto-wrapping temporarily when sending <CR> and resume auto-wrapping after that. There are multiple ways of doing that. And the best one as far as I know is using the paste mode, since you don't have to exit insert mode when entering paste mode. So just make the following commands into any key binding you like in insert mode. The one I am using right now is inoremap <C-N> <F2><CR><F2>
The reason why I think this one is not optimal is that for some reason I cannot bind <Enter> in this way, but have to use another key.
If <Enter> or <CR> can be configured in this way then the problem is 100% solved.
I would like vim to scroll horizontally like nano does, by scrolling only the current line, not the whole screen.
I tried playing with nowrap and scrolloff settings, without success.
Here are some screenshots (with the cursor at the end of a long line) to explain myself.

Vim (wrap):
Vim (nowrap):
Thanks!
No, Vim cannot do this, and I think it would be hard to implement this in a way that isn't inconsistent or confusing to the user. There would need to be an indicator (like with side scrolling) that only the current line is scrolled. Also in Vim, there are several commands (like j / k and i_CTRL-Y / i_CTRL-E) that refer to the same column in above / below lines. A partially scrolled view state would make it difficult to use those.
That said, you can sort-of achieve this with a hack: The foldtext of folded lines does not scroll horizontally. So if you fold each individual line (other than the current one) via a custom 'foldexpr', set the fold text to be the line's text, and automatically close all surrounding folds, you'll get this. However, as you'll lose syntax highlighting and "normal" folding, this is more for demonstration than an actual solution.
ReSharper has a nice feature called "extend selection": by pressing CTRL+W (I think this is the default) repeatedly, you select more and more from your current caret location. First it's a word, then more and more words, a line, inner then outer block of lines (for example an if-block), then a function, etc...
Basically, by pressing the key combination repeatedly, you can end up selecting the entire file. I'm sure at least some of you will be familiar with it.
I have just started learning all the intricacies of vim and I don't have enough experience to see how something like this could be implemented in Vim (although I assume it's possible). So my question is meant for Vim gurus out there: can this be done and how?
Update: a bit of a background story. I've been talking to my ex-boss about all the benefits of Vim, and he thinks it's all great. His only question/problem was: does it have "extend selection"? My question so far has been no. So, if someone knows the answer, I'll finally win a discussion :P (and maybe create a new Vim convert:-))
I had a quick go at this problem. It doesn't work as is. Feel Free to make edits and post on the vim wiki or as a plugin if you get it refined.
chances are you'd want to make a g:resharp_list for each language (eg. one for paranthesised languages, etc.)
All that is needed is a marker for the original cursor position :he markers and a timeout autocommand that resets the index.
"resharp emulator
"TODO this needs a marker
"also c-w is bad mapping as it has a lag with all the other-
"window mappings
"
let g:resharp_index = 0
let g:resharp_select = ['iw', 'is', 'ip', 'ggVG']
func! ResharpSelect()
if g:resharp_index >= len (g:resharp_select)
let g:resharp_index = 0
endif
exe "norm \<esc>v" . g:resharp_select[g:resharp_index]
let g:resharp_index = g:resharp_index + 1
endfun
nnoremap <c-w> :call ResharpSelect()<cr>
vnoremap <c-w> :call ResharpSelect()<cr>
"Something to reset on timeout. TODO this doesn't work
au CursorHold :let g:resharp_index = 0<cr>
The answer is yes. Once in Visual mode you can use all the regular navigation methods as well as some extra ones.
Some of my favourites? First hit v while in normal mode to get to visual mode then hit:
iw - to select the inner word. Great for selecting a word while excluding surrounding braces or quotes
w - hit multiple times to keep selecting each subsequent word.
b - select wordwise backwords
^ - select all from current position to beginning of text on line
$ - select all from current position to end of line
I'm sure others here could add to this list as well. Oh and don't forget Visual Block mode C-v try it out in vim with the above commands it works in two dimensions :-)
If you're talking about Vim (and you should be :-), you can start marking text with the v command, then you have all the standard cursor movement commands (and, as you know, there are a lot of them) which will extend the selection, as well as moving the cursor.
Then you just do whatever you want with the selected text.
See here for the gory details.
One would need to write a function that would save the current selection, then try increasingly wide selections, until the new selection exceeds the saved one or selects all text. Some possible selections are:
viW - select word
vis - select sentence
vip - select paragraph
viB - select text within the innermost brackets
v2iB - select text within the next most innermost brackets
ggVG - select all text
I think Jeremy Wall's heading in the right direction. And to get a little further in that direction, you might look at the "surround.vim" script from Tim Pope. A good description is available on github. Or, if you'd rather, get it from vim.org. It'll probably help you do some of the things you'd like to do, though it doesn't seem to have a feature for say, simply selecting within a tag. Let me know if I'm wrong.
Ultimately, what you'd really like is a hierarchy of enclosing text-objects. You should read up on text-objects if you haven't. A nice overview is here. Note that you can grab multiple objects in one go using counts, or do this iteratively (try vawasap}}} from normal mode).
You can also get scripts which define other text-objects, like this one that uses indentation to define a text-object. It'll work for many languages if you're formatting according to common standards, and guaranteed for python.
One annoyance is that the cursor ends up at the end of the visual block, so, for example, you can't easily select everything between some ()'s, then get the function name that precedes them...
...BUT, I just found in this post that you can change this behavior with o. Cool!
I suspect you'll find yourself more efficient being able to skip over intermediate selections in the long run.
Anyway, I'll be curious to see if anyone else comes up with a more general solution as well!
In Rider [on a Mac with VS Mac bindings with IdeaVim], I bind:
Ctrl+= to Extend Selection
Ctrl+- to Shrink Selection
Doesn't clash with any other bindings of consequence and doesn't require a v for mode switching, and easier than Cmd+Option+-> and Cmd+Option+<-
Putting it here as I always hit this question with any Rider Vim selection searches. If I get enough harassment, I'll create a self-answered "How to use Extend Selection with Rider Vim mode".
Is there a way to keep the cusror location off-screen in Vim / gVim while scrolling? Similar to many Windows editors.
I know about marks, and do use them. I also know the '.' mark (last edit location), But looking for other ideas.
I'm asking this because sometimes i want to keep the cursor at some location, scroll to another place using the mouse-wheel, and then just press an arow key or something to get me back to that location.
No. vim is a console application, so it doesn't really make sense to have the cursour off-screen (it's possible, but would just be confusing)
An alternative solution, to paraphrase posts from this thread from comp.editors:
Ctrl+o goes to the previous cursor location, Ctrl+i goes to the next (like undo/redo for motions)
Marks seem like the other solution..
Also, use marks. Marks are named by letters. For instance typing ma remembers
the current location under mark a. To jump to the line containing mark a,
type 'a. To the exact location use `a.
Lower-case-letter marks are per-file. Upper-case-letter marks are global;
`A will switch to the file containing mark A, to the exact location.
Basically ma, move around, then `a to jump back.
Another option which Paul suggested,
gi command switches Vim to Insert mode and places cursor in the same position as where Insert mode was stopped last time.
Why don't you split the window, look at what you wanted to look at, and then close the split?
:split
or
:vsplit (if you want to split vertically)
The only similar behavior that I've found in Vim:
zt or zENTER "scroll the screen down as far as possible without moving the cursor"
zb "scroll as far up as possible".
Ctrl+E "scroll one line down, if possible"
Ctrl+Y"scroll one line up, if possible"
Sometimes you can avoid jumping to marks before entering text — gi command switches Vim to Insert mode and places cursor in the same position as where Insert mode was stopped last time.
Google says that the cursor (and therefore current line) must be visible in Vi, so you'll have to use marks.
Also very useful are the '' (2x single quotes) and `` (2x back quotes).
The former jumps back to the line you were prior to the last jump (for instance, a page down).
The latter jumps back to the line and column you were prior to the last jump.
