VIM -Change waiting time for combined key maps

Question

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?

:help timeout should give you all the information you need. Specifically, the timeoutlen setting does what you want.
