I'm sure there are other ways to do this, but here is the way I do it
Create a button, hotkey, picture, or whatever else you can assign a macro to and then show the form from the macro.
If you are not sure how to do this:
Click on your form and check it's properties for the name given if you did not name it yourself. If it is the only form in your project, it will be called form1...
Anyway, in the macro type:
form1.show
Replace form1 with the name you gave your form in necc.
