If I'm in insert mode in Vim, and I press Control + W, it waits a moment, then deletes the previous word. If I start typing immediately after pressing it, it deletes the previous word instantly and replaces it with what I type.
In either case, the previous word is deleted and whatever I type next replaces it. So why the pause? Is there something else I can do at that point?
Update
This is on MacVim 7.3 (55) on OSX Snow Leopard. I just logged into a server with a vanilla config and tried it, and the deletion is instant. So maybe it's something with my config?
