如何更改重音字符的vim映射

Question

I am trying to change vim mappings for (french) accentuated characters.

à (ASCII 133) I would like it to be Alt + a
À (ASCII 183) I would like it to be Alt + Shift + a
é (ASCII 130) I would like it to be Alt + e
É (ASCII 144) I would like it to be Alt + Shift + e

I would be happy to remap the existing maps Alt + i ==> é (why is that?)
How can I get those mappings to work ?

Answer 1

mapping works for theses chars, and the question is about the alt key, which may not work when the terminal prefixes the character with an ESC character. type :help map-alt-keys for more informations on that.

I just tried in xterm and theses mapping worked:

:imap <A-a> à
:imap <A-A> À
:imap <A-e> é
:imap <A-E> É

And also, for changing default mapping to another, use "remap" instead of map :

:iremap <A-i> whatever
