In VIM, When I map for example <F9><F10> to a command and <F9> to another command , it waits for 1-2 seconds when I press F9 to allow me press <F10> to access the command mapped to <F9><F10> and if I don't press <F10> it executes the command mapped to <F9>.Is there a way to change this waiting time?
