xterm中vim中的功能键

Question

Functional keys (F1-F12) for vim in console don't work. But the worst thing is when I hit such key, vim stays in some "mode" not allowing me to type anything for 2s... Very annoying

Another thing is after pressing Esc key vim pause for about 0.5s before go to normal mode.. But this is only happening in screen , even I set

export TERM=xterm

Anybody has some clean and short solution?

Answer 1

Sounds like some disagreement between the byte sequences vim thinks the terminal is going to send, and the sequences it actually does.

Also the half-second delay is a consequence of having some mappings that start with Escape.
