LabVIEW
I want to press the enter key and the buttons on my VI switch until enter is released.
A mechanical action of "switch until released" is probably not the right mechanical action. Why do you think it is?
Try latch action and make sure the terminal is in the location where it is read by the code to properly reset.
We can give more specific advice once you attach a simplified version of your VI (Make sure to "save for previous, 2020 or below). What do the buttons actually do?
Are you using an event structure, or could you add one?
If so, you can use the Key Down and Key Up events to both capture which control has focus (i.e. it was tabbed to) and if the key pressed was the Enter key or not:
You can then use that to do... whatever it is needs to be done when someone presses Enter.

I have tried every other mechanical action and they all work the same way with enter as a key activation.
Latch action booleans reset back to the default state when the terminal is read by the code, so if the terminal is e.g. on the toplevel diagram outside the toplevel loop or hidden inside a case that does not execute, it will never get read during run. If they are linked to an event, it is best to place the terminal inside that event. (We also need to assume that your architecture is sane and the event is always ready to execute and not hidden in structures or other parts of the diagram that are blocked by dataflow.)
"XXX until released" acts like a car horn such that the value is TRUE as long as you hold the button down with the mouse (and if you use an event structure, you'll get two events, one on press and one on release). But if you poll it, you might get multiple TRUEs or miss it completely, depending on the loop rate and other factors. If you really (really!!!!???) want to duplicate that with keys (i.e. do "something different" as long as the key is held down), you can implement anything you want with some code, of course.
With questions like that, it helps to give some context on what these buttons actually do.
Do you want to toggle the state of the button from "unpressed" to "pressed" one single time when you press Enter, or do you want the button held down the entire time you're pressing and holding Enter?

When I just click and release with the mouse, the button presses then depresses on it's own. When I press enter and release, the button stays down instead of coming back up. I want it to have the same actions as with the mouse.
We seem to be going in circles. Why don't you attach a simplified VI to show us what you are doing. My guess is still that you are not using the correct mechanical action and have poor code architecture.
I think that the requirement to use the Enter key as well is going to make it tricky because you will have to guard against someone leaning on the Enter key and causing multiple Enter key events. This doesn't happen with button presses because the event doesn't fire until the button is released.
