Hi,<br><br>the underscore (_) is a typical map-leader (the LHS of mappings typically starts with an _). However, for some reason it cannot be used in vim on vms.<br><br>Example:<br>:map _h :echo "hi"<CR><br>
<br>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).<br>
<br>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.<br><br>
