How open help in the current window?

[Peng Yu]

Hi,

When I open help by ":help", it will add a new window for help. Is
there a way to replace the current window with help? Thanks.

Regards,
Peng

Hi !

I don't thinks it's possible, as the help window is a specific window.
Anyway, you can get the help window to fit the whole page by focusing it
and press <C-w>_

Regards,

Willy

This has unfortunate side-effects if you have multiple windows open.
Yukihiro's solution using ":set buftype=help" is the closest I've seen
to solving the OP's request (despite the warning in the help for
'buftype' that tells you it shouldn't need to be set manually) though
if the buffer has been modified, vim will warn you rather than losing
your changes. There doesn't seem to be a ":help!" (well, there is,
but it doesn't abandon changes in the buftype=help window; rather it
attempts to console you in your panic :-)

Good point. I often use that when opening a new vim instance just
to read help. I wasn't thinking about the multiple window case.

And my intent was not to discredit your answer either, since I
too do :help/:only far more than I've ever twiddled the 'buftype'.
It just does something different than what the OP asked. :-)

I have this mapping in my vimrc:

" Open help in a separate tab with <F1>
noremap <F1> :<C-U>tab help<CR>

This way I can just hit <F1> for full-screen help.
