Re: (Bug ?) Sometimes { in insert mode triggers normal mode

Hi Tim,

I realized that the issue was due to a wrong keyboard layout.

This sounds suspiciously like somehow control+[ is getting pressed
(which sends the same key-code as escape).  Is there any chance you're
holding down control rather than shift when this happens?  If you
log keystrokes at the OS level (such as with one of those used in
screen-casts), does it report control+[ instead of shift+[→escape?
It could also be a keyboard issue where a faulty contact is sending
control-modifier rather than a shift-modifier, so if you can try it with
a second keyboard (if you have a spare USB keyboard or can borrow one
for testing), it might help narrow things down.

(Bug ?) Sometimes { in insert mode triggers normal mode

Hello,

I have noticed (on Linux) that pressing `'{' in insert mode, vim/gvim sometimes triggers the normal mode: I mean vim goes from insert to normal mode.

I do not have any mapping related to '{' in insert mode neither in normal mode.

The current version testes is v9.1.0764, but I noticed the problem also with v9.1.0748.ç

Cheers,

Simon

Re: Finding all words

Very good idea. Thanks again.

At the cost of some redundancy, you might be able to speed it up a
little bit by requiring that it start with at least one of the words
like

  /\%(\<\%(quick\|brown\|lazy\|jumps\)\>\)\@=\%(.\{-}quick\&.\{-}brown\&.\{-}lazy\&.\{-}jumps\)/

so it won't start looking for the other terms until it's found at
least one of them, cutting out a lot of non-starter cases.

That finds *any* of the words, not *all* of the words as the OP requested.

While the implementation can often end up slow if you have a large
text or lots of find-them-all terms, you (OP) can use

   :help /\&

to join the conditions like

    /.\{-}quick\&.\{-}brown\&.\{-}lazy\&.\{-}jumps/

-tim

Thank you; that's exactly what I was looking for. It does slow down, though, as you said it might, once I add more words to it. I might write something that does the combination thing I was suggesting and time the two approaches, but with more than just two words: /quick.*brown\|brown.*quick/ vs. /.\{-}quick\&.\{-}brown}/ 

Best regards,

Salman
