However, for some reason it cannot be used in vim on vms. Example: :map _h :echo "hi"<CR> In my gvim on Windows, when I create the mapping above, and then start typing "_h", vim knows that "_" is the prefix of a mapping, so it does not apply/type the "_" immediately. Instead, it cashes the keypress and displays the "_" in the bottom-right corner. That means, vim is waiting for the next key - if it is an "h", vim will apply the _h mapping; if it is an "o", vim will type "_o" (since there is no mapping for _o). However, this does not work on vms: the _ gets applied/typed immediately (it is not cashed). Thus, typing _h does not apply the mapping, but performs the "_" action and then the "h" action.

(The description in #11 seems more to the point.) Mon, 06 Dec 2010 11:18:00 +0100 http://www.polarhome.com/horde/whups/ticket/?id=5#t23
