Google should provide me with ample examples but none of them seem to work
What I want: Everytime the user presses, and then releases, the ENTER key
First, make an callback Sub that performs the logic you need. Put it into a new code module (NOT into worksheet code):
Sub SomeActions()
...
End Sub
Then, subscribe to OnKey event, for example, when the user opens the workbook (this code goes into ThisWorkbook) module in VBA editor:
Private Sub Workbook_Open()
Application.OnKey "~", "SomeActions"
End Sub
"~" means Enter key. For numeric keypad key use "{ENTER}".
