How to move screen without moving cursor in Vim?

问题:

I recently discovered Ctrl+E and Ctrl+Y shortcuts for Vim that respectively move the screen up and down with a one line step, without moving the cursor.

Do you know any command that leaves the cursor where it is but moves the screen so that the line which has the cursor becomes the first line? (having a command for the last line would be a nice bonus).

I can achieve this by manually pressing Ctrl+E (or Ctrl+Y) the proper number of times, but having a command that somehow does this directly would be nice.

Any ideas?

• zz - move current line to the middle of the screen
  (Careful with zz, if you happen to have Caps Lock on accidentally, you will save and exit vim!)
• zt - move current line to the top of the screen
• zb - move current line to the bottom of the screen

Additionally:

• Ctrl-y Moves screen up one line
• Ctrl-e Moves screen down one line
• Ctrl-u Moves cursor & screen up ½ page
• Ctrl-d Moves cursor & screen down ½ page
• Ctrl-b Moves screen up one page, cursor to last line
• Ctrl-f Moves screen down one page, cursor to first line

Ctrl-y and Ctrl-e only change the cursor position if it would be moved off screen.

Vim requires the cursor to be in the current screen at all times, however, you could bookmark the current position scroll around and then return to where you were.

mg  # This book marks the current position as g (this can be any letter)
<scroll around>
`g  # return to g

To leave the cursor in the same column when you use Ctrl+D, Ctrl+F, Ctrl+B, Ctrl+U, G, H, M, L, gg

you should define the following option:

:set nostartofline

Here's my solution in vimrc:

nnoremap k kzz
nnoremap j jzz
nnoremap p pzz
nnoremap P Pzz
nnoremap G Gzz
nnoremap x xzz
inoremap <ESC> <ESC>zz
nnoremap <ENTER> <ENTER>zz
inoremap <ENTER> <ENTER><ESC>zza
nnoremap o o<ESC>zza
nnoremap O O<ESC>zza
nnoremap a a<ESC>zza

So that the cursor will stay in the middle of the screen, and the screen will moves up or down.

You may find aswers to this question useful: Scrolling Vim relative to cursor, custom mapping: you can use ScrollToPercent(0) from that question to do this.

回答7:

You can prefix your cursor move commands with a number and that will repeat that command that many times

10Ctrl+E will do Ctrl+E 10 times instead of one.

回答8:

Sometimes it is useful to scroll text with K and J keys. So I have this "scroll mode" function in my .vimrc (also binded on zs)

scroll_mode.vim

zEnter does exactly what this question asks for.

It works where strangely zz would not work (vim 7.4.1689 on Ubuntu 2016.04 LTS with no special .vimrc)

There is a new plugin which I wrote, it enables you to navigate the hole file without moving the cursor position. It's based on folding the lines between your position and your target position and then jump over the fold. Or abort it and don't move at all.

It's also easy to fast switch between cursor is the firt line, cursor is the last line and cursor is in the middle by just clicking j, k or l (when you are in the mode of the plugin.)

I guess it would be a good fit here: https://github.com/anschnapp/move-less
