vim smart tabbing

In emacs, whene开发者_运维知识库ver tab is pressed, the cursor moves to the appropriate location on the current line. However, in vim, this does not happen, the tab is a given length and will go that far every time I press tab. Is there a way to enable "smart tabbing" in vim?

I'm not exactly sure what behavior you expect, but this is probably it.

:set smarttab

Also consider setting:

:set smartindent
:set autoindent

I assume your question is the following. You have text like:

This is line 1

$ (lots of white space) This is line 2

This is line 3

Now, you are in normal mode, your cursor is after $, and you would like it get just before T. If so, just press 'w' (to traverse a 'w'ord) and you would achieve your objective.

Perhaps you just want to use == to auto-indent the current line.
