dynamically

I'm currently evaluating SyntaxEditor for our company's custom language.

I'm trying to dynamically update the intellipromptmemberlist (i.e. culling out symbols based on what the user is currently typing) by adding entries to the member list while the intelliprompt member list is displayed, but I get this exception:

Additional information: The IntelliPrompt member list cannot be modified while it is displayed.

I also want to remove items in the list, but there's no remove function in IntelliPromptMemberList.

What's the recommended procedure for dynamically updating the member list?

Also, I need to just depoly intelliprompt member lists when the user types any key (since our language just has global functions.) I've added a key trigger for each key press (a-z and A-Z) This works, except it keeps the first letter that the user types. What's the recommended way to make sure it doesn't keep that first character?

Thanks!
