System and IINA version:

• macOS 12.3.1
• IINA 1.2.0

Expected behavior:
When a key is pressed IINA executes the commands assigned in a custom key binding.

Actual behavior:
IINA ignored the key binding.

Steps to reproduce:

• Open IINA / Preferences
• Click on Key Bindings
• Select IINA Default
• Click Duplicate
• Click + to add a new binding
• Add an additional binding for the RIGHT (arrow) key with the action seek 60 exact
• Add an additional binding for the LEFT (arrow) key with the action seek -60 exact
• This adds a second definition for these keys
• Restart IINA to insure new preferences are being used
• Play video
• Open Playback menu
• Notice that the menu item Step Forward 5s is still bound to the right arrow key
• Notice that the menu item Step Backward 5s is still bound to the left arrow key
• Test the right and left arrow keys
• New binding are ignored and IINA continues to seek by 5 seconds

• MPV does not have this problem.

This is a problem in IINA.

How often does this happen?
Every time.

I will post an analysis of the root cause and a proposed fix.
