Vim确定将哪些映射分配给键

Question

My 'O' command (enter a new line above this one and enter insert mode) is slow to take effect. It seems like this is because there is some other mapping, such as 'OP' , and that vim is waiting when I hit 'O' to see if I want 'O' or 'OP'. I don't know what set this mapping, it's not anything in my .vimrc. I'd like to find it and change it so I can go back to having snappy 'O' commands, but I don't know how to find it.

Is there a way to see a list of what mappings a key is involved with? Note: I do not want to reduce my timeout setting.

Thanks

Answer 1

:verbose map O

tells you which mappings start with O . That usually gives you the right hint about mappings that execute only after a short delay. For the O mapping in particular, you may also suffer from the problem described in delay before o opens a new line .
