Pass to Default - Would send an altered version of recieved text to the default processing for an event. Thought of this earlier but can't think of an example now.
Clear Typed History - Would clear the entire typed history (for a specific window or all windows).
A Typed Histroy Identifier - Would provide the N typed history entry.
If some/all of these exist, I appologize. I tried to find them in the help, but to no avail.
