如何在Vim中不移动光标的状况下移动屏幕？ - 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 . 最近，我发现了Vim的Ctrl + E和Ctrl + Y快捷键，它们分别以一个一行的步长上下移动屏幕， 而不移动光标 。

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? 您是否知道有任何命令将光标留在原处但移动屏幕，使具备光标的行成为第一行？ (having a command for the last line would be a nice bonus). （在最后一行输入命令会是一个不错的选择）。

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. 我能够经过手动按Ctrl + E （或Ctrl + Y ）适当的次数来实现此目的，可是使用某种能够直接执行此操做的命令会很好。

Any ideas? 有任何想法吗？
