Yup and yup.
Have you downloaded the installer package with the configurator? If not I suggest you do.
To make the button send a keystroke:
a) make a brain instance
b) make an analogue input instance
c) start a new logic block
d) make the logic layout as shown in the first picture
e) click the "what to do" button (the judgment icon)
f) add a new do statement and select "send key" for the what to do part
To change the maximum times per second it fires, click the time icon on the logic block
g) and then there you change the time for the minimum time between firing. So if you set it to 100, then it can only send the key 10 times a second. Change it to 1000 and then only 1 time per second. Change it to 60000 and it will only fire 1 time every minute. and so on.
