I use the Alt-Latin keyboard layout (set in OSX) to write diacritics in Vim. This layout uses combinations with the Alt and Shift keys for modified letters. For example <A-.> followed by a letter prints that letter with a dot below, e.g. . Now, in Vim, some of these combinations are overridden, so that in <A-.> prints , for example. How can I disable these key combinations in Vim to get the combinations of the layout as defined in the OS. This is a follow-up of a previous question (which I deleted) in which I wrongly assumed that this had something to do with diagraphs.
