Donald,

What I would suggest here to slow down the loop, is to make use of the built-in
tasking features of Euphoria. Here is a quick example I mocked up.

procedure check_key()

    while 1 do
        if get_key() = ' ' then
            -- user pressed space bar
            exit
        end if
        task_yield()
    end while

    -- simpler version:
    --while get_key() != ' ' do
    --  task_yield()
    --end while

end procedure

integer check_key_task

    -- create the task, no parameters required
    check_key_task = task_create( routine_id("check_key"), {} )

    -- adjust timing here:
    -- (this would be one hald to a whole second)
    task_schedule( check_key_task, {0.50,1.00} )
    
    -- loop while the task is 'active'
    while task_status(check_key_task) = 1 do

        -- do important stuff here,
        -- this loop will automatically exit
        -- when the user presses the space bar
        
        task_yield()
    end while
