4.18p4 Use the provided BugDemoV8 project for faster demonstration. 1. Open Sequence. 2. On the PostProcessVolume item use the + button and Add a “Blend Radius” Track. 3. Select the new “Blend Radius” Track, Ctrl-X & Ctrl-P will Crash the Editor. Note after the Ctrl-X/Cut command, the parent PostProcessVolume item is no longer selected, so there is no destination for the Paste. However, some Tracks such as Visibility, Paste to the root without a crash. Most Tracks do crash. Sequencer should check for empty Paste selection not to bring down the Editor so easily. ---

The keyboard focus is generally quite erratic in UE. This crash can easily be triggered, with Ctrl-X an P unintentionally sent to the Sequencer. Even using the Sequencer toolbar can steal the keyboard focus, so basic keyboard commands, like Spacebar for Play will become disabled quite often. Editing a property in Details panel will steal the focus frequently, needing a click back in the Sequencer or Cinematic Viewport just to use the Spacebar Play/Pause again. Play/Transport keyboard commands are critical with Animation/Music editing software, so all these extra clicks are unusual and unprofessional. There should be some global key modes that are sent to the Sequencer, if not consumed by a text field, etc. The numeric fields should also implement the mouse wheel for faster adjustments. I should probably post these suggestions separately. ---
