Description:

I found what appears to be a bug in Cartoon Animator 5.34.

Steps to reproduce:

Open a project.
Select the Camera track.
Go to Camera > Transform in the Timeline.
Select one or more Transform keyframes.
Press Ctrl+C and then Ctrl+V.

Expected result:
The selected Camera Transform keyframes should be copied and pasted, just like keyframes on other tracks.

Actual result:
Nothing happens when using Ctrl+C or Ctrl+V.
However, right-click → Copy and right-click → Paste work correctly on the exact same keyframes.

Additional information:

Cartoon Animator version: 5.34
The keyboard shortcuts are correctly assigned to Ctrl+C and Ctrl+V.
Ctrl+C / Ctrl+V work normally on other timeline tracks (Sprite, Motion, Transform, Opacity, etc.).
The issue occurs only on the Camera > Transform timeline.
Since the context menu commands work correctly, this appears to be a keyboard shortcut handling issue specific to the Camera Transform track.
