But what if you don't want to break on a specific line but instead break when you hit a particular function?  No problem!  There are three ways to do this:

One

Right-Click a function name and go to Breakpoint -> Insert Breakpoint

Two

In the Breakpoints Window, Click on the New button and choose "Break at Function" to bring up the New Breakpoint dialog.

Three

Press CTRL + B to bring up the New Breakpoint dialog.

Options Two and Three will take you to the New Breakpoint dialog.  Here you can type in the name of the function you want to break at then click OK.  Using any of these methods you will see something similar to the following when you are done:

And there you have it!  Setting a breakpoint on a function.

    My default VS 2010 shortcut was Ctrl + D, N, not Ctrl + B. Maybe because I am using VS 2010 RC.

    user, the shortcuts can be different depending on which "mode" you selected as the default when you first started VS. In order for a breakpoint to work when it is set on a DLL for which you don't have debugging symbols, you need to have Tools>Options>Debugging>Native>Load DLL Exports enabled.  Otherwise, the breakpoint will be set but will never stop.  It took me quite a while to find that one the last time I tried to set a breakpoint on a DLL function when I didn't have symbols.
