I'm sure it is quite indistinguishable.
The default is 960 ticks per quarter note. Go to Options>Project Options to see this.
That number is a variable, so double check the clock settings.
I just tried it, and inserting 960 ticks gives me a quarter note void.
I assume you realize that this will shift the following clip(s) 1/4 note later in time.
You can also set the onscreen clock to M:B:T (Measures:Beats:Ticks) to get a better idea of how the ticks fit in.
