flyspell-delay-command
flyspell-delay-command is an interactive compiled Lisp function in `flyspell.el
'.
(flyspell-delay-command COMMAND)
Set COMMAND to be delayed, for Flyspell.
When flyspell `post-command-hook' is invoked because a delayed command
has been used, the current word is not immediately checked.
It will be checked only after `flyspell-delay' seconds.
