Sorry I attached wrong file. See the attached.

Please give files a new and unique name whenever attaching a modified version.

This avoids confusion on what's what. Thanks.

I don't see any key up/down events in your latest attachment, so I don't know what you are saying.

altenbach, see the attached "repeat event key.vi". I used key up and key down for the "send" button, but don't see event triggered. Thanks.

Which key are you pressing? (You probably need to ensure that the button has key focus)

What is the point of the waits?

[guangdew1]

This is the for "send" button. There's some comfusion about key and button, is it that button means on display front panel and key means keys on keyboard? I don't know whether the key up/key down event will respond to the front panel button press, I know it's a value change.

The wait is the interval between sending commands. 

Is it that this "send" button key up or down event is keyboard key up or down when the "send" button has key focus.

[altenbach]

Yes, the button needs key focus first. Nothing repeats, because to get another key down event, a key up needs to happen first.

For a front panel bottom press, use mouse down or value change events. (Value change preferred).

To use keys, use general key down events, not tied to a control.

I have touch panel in mind. I know mouse click on a button is equivalent to a touch panel finger press on a button, but I don't know whether the mouse event will apply.
