I use SendKeys as a last resort. It may work for you but I always try to develop my apps to work using Tab, Enter, and the Arrows. There is little need for the mouse. For instance, set the tab order of your form's controls so the focus of the cursor cycles through fields and ends on a series of Command Buttons. A commond button can execute code. It could launch a message box for user input or simply execute without a prompt.
If you want to try SendKeys, here is some reference

Here is some code I use to simulate the Enter key being pressed.
Code:
Dim MyEnterKey As String
MyEnterKey = "~"
SendKeys MyEnterKey
