Unfortunately, LV doesn't allow you to map arbitrary key strokes to particular key. The closest it gets is letting you assign funtion keys (F1 through F12) to controls.

Still, there might be a way to get what you need. There are VIs available that allow you to trap characters typed on the keyboard. Perhaps they might help.

I attach one file for you, but my VI is no need CTRL you just type the value. I think there should be a better way to do it. Anyway here is my VI..

LabVIEW does not allow such shortcuts to be assigned to controls etc, only menu items. However you can use the key down event to detect when the given key combination has been pressed and then highlight the control, press down boolean control or whatever it is you want the keyboard shortcut to do...

An example showing how to read the key down event can be found at:

As the other posts mentioned, LV allows for FKeys and some other common
keys to be attached to buttons, and it allows for ctl-key combos to be
assigned to menu items.

This separation may change in the future, but it was done this way
because those are typical UI guidelines for UI key navigation. You
might want to consider whether you want to make a menu item that carries
out the same action as the button and make the key combo do the menu
instead of the button. Even when the menu is hidden, such as in a
Windows modal dialog, the menu shortcuts are still active.
