Answer Wiki:
You could use the KeyPress, KeyDown, KeyUp events.
If you are going to manage these events at the form level, you might want to set the KeyPreview property of the form to 'true'.
Example:
<pre>Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)
If KeyCode = 37 Then
MsgBox ("The left arrow was pressed")
End If
End Sub</pre>
Please provide more details if you need further help.

I would avoid the KeyPress or KeyDown events unless you really understand what these mean and have a specific need to process these events. When you play with the KeyPress/KeyDown events, you need to worry about the states of multiple keys (shift, alt, fn) and it is real easy to get wrapped around the axle with recursive event entries.
It is MUCH safer to handle Change events, or if you must deal with key events, I would suggest using the KeyUp event, which will only occur once per key press. By waiting until the user releases the keys, the event handling is much simplified.
