LabVIEW
Prompt User for input - enter key approve
I'm not a fan on the Prompt User For Input. Make a VI to be your dialog. It can be really simple. You can also link the OK button to the enter key.
Please explain what kind of inputs you have configured, because the workaround depends on it!
In the standard express VI you are using, <enter> cannot be used in general, because you might have multiple fields and enter will terminate the input for each. You would not want to terminate the dialog after just one has been modified. (Besides, that express VI dialog is extremely ugly. I would never allow that in my programs!)
How is your express VI configured and how many fields, and what types? You typically would get much more targeted help of you would make it a habit to attach a simple VI explaining the problem.
It is trivial to write your own dialog box that reacts to <enter> the way you want. If the input is a string, set to to "limit to single line" Use event structures for value change and terminate the dialog when a vale has changed.
You don't need any property nodes to do what you're trying to do IMO. Without seeing your VI, here are the steps I think you should try:
1. Configure your Prompt user for input Express VI as much as you want, with the message to appear, the inputs and so on.
2. Right click the Express VI and Open Front Panel. You'll be asked to save this, as you are essentially creating a VI of your own with the configured ExVI as the starting point.
3. Go to the front panel and right click your OK1 button (I assume you've configured your VI to not show the cancel button, so this is the one you want to modify the behavior of). Click Properties, and go to Key Navigation all the way to the right. I've attached a picture of the default key navigation behavior of Prompt User for Input ExVI. OK2 and Cancel have default bindings already.
4. What you want to configure is the Toggle setting. That is where you can set a key combination that will immediately toggle the button and stop the VI.
5. Clean up the extra junk you don't need, mostly from OK2 and Cancel buttons not being needed if you don't need them and save the VI. You could add whatever UI enhancements you want as well, the one I'll mention is to only enable the OK button if all fields have something in them.
What you normally think of as the Enter button is actually called Return in LabVIEW and I'm sure in a lot of other places too. The Enter key next to your number pad is the one called Enter. You can see this for yourself with an event structure, a key down event, and an indicator on VKey.
They are definitely not the same key, although in most cases they function the same. The main difference in behavior in my experience is that with labels and comments, Return moves you down a line and Enter actually "completes" the text. For some (good, I'm sure) reason, they don't offer both of those as options to toggle, instead just offering Return and having both keys respond to that.
Modifiers just make it to where the user has to click Shift+F4 or CTRL+F5 or CTRL+Shift+F6 etc., for the toggle to happen.
