Hello,
Backspacing or typing while the Vim 7 Insert completion popup window is running
is very difficult when the completion list is long or comes from many sources.
Because the popup menu refreshes itself on each backspace, each keystroke can
take up to half a second to appear, and it was actually easier to hit escape
and re-enter insert mode to stop the popup menu guzzling CPU cycles on each
keystroke.
Miraculously, it was very easy for me to create an extra value for
'completeopt' which stops the popup menu as soon as something is backspaced or
added, and allows me to have the popup menu turned on, but without it getting
in my way as I type.
Do you think it would be worthwhile adding this patch into Vim?
regards,
Peter
