If keyboard or shortcut keys aren’t working during editing, try the following:
Make sure the Cutback window is active. Inputs may not work if another panel is in focus.
There may be a conflict with Premiere Pro shortcuts. Try closing and reopening the Cutback panel.
If language switching (e.g., Korean/English) doesn’t work, it’s a known issue with Premiere Pro.
Quit Premiere, switch the input language at the system level, then reopen Premiere.
