+\begin{funcdesc}{typeahead}{fd}
+Specifies that the file descriptor \var{fd} be used for typeahead

+The curses library does ``line-breakout optimization'' by looking for
+typeahead periodically while updating the screen.  If input is found,
+and it is coming from a tty, the current update is postponed until
+refresh or doupdate is called again, allowing faster response to
+commands typed in advance. This function allows specifying a different
+file descriptor for typeahead checking.

+Sets blocking or non-blocking read behaviour for the window.  If
