One question I hear often is asking if there is a way to tell what filters are applied to a clip by looking at the clip in the Final Cut Pro timeline. The answer is yes. You must first turn on the Toggle Clip Keyframes button in the lower right corner of the timeline, or use the keyboard shortcut Option + T:

Next, right click (or control + click if using a one button mouse) on the tiny little horizontal green bar that pops up under the clip in the timeline. There you will see a list of all the filters applied to the clip:

If you know you have filters applied to a clip but they don’t show up when the performing the above steps the option might be turned off. Right click (or control + click if using a one button mouse) on the Toggle Clip Keyframes button in the timeline and you will see options for what can be displayed in the timeline:

Check marks indicate what is currently displayed. The timeline indicators and options are powerful tools that are often overlooked.
