Hi
...or Just zoom into the timeline using the mouse scroll wheel.
Initially your project is fitted to the screen width. This means that If you have a lot of clips on the timeline they are initially "squashed" up and some (even all) can individually be too narrow to show the Transition X, the FX or the f. Zooming in will spread them out.
Alternatively switch the display into Storyboard mode. The clips, (on Video Track 1,) irrespective of their actual duration, will now be displayed as a single thumbnail with a large transition X between them and FX and f controls below each one.
Either way you may have to scroll right or left to locate the area of the timeline you require.
