Clearing a Breakpoint
To clear a breakpoint, left-click on the red dot next to the line of code that has the breakpoint.

In this example, we want to clear the breakpoint at the following line of code:
If IsNull(cboKeyword) = True Then

Now, the breakpoint is cleared and the line of code should look normal again.
