Current Behavior

When capslock is activated, IME will turn into English input, pressing "Enter" isn't creating a new text block, but line break is inserted.

Expected Behavior

Pressing "Enter" key should creating a new text block instead of inserting a line break.

Steps To Reproduce

1. Use Chinese IME or any other IME that can use Capslock to turn into English mode
2. Press "Enter"
3. Line break is inserted

Environment

- OS:macOS 15.6 
- Version: 0.49.8

Anything else?

Root Cause Analysis

I've confirmed the problem is on pressed key detection logic on /src/ts/component/block/test.tsx > BlockText > onKeyDown (L1038).

			// Enter
			keyboard.shortcut('enter, shift+enter', e, (pressed: string) => {
				if (isInsideTable && (pressed == 'enter')) {
					this.onArrowVertical(e, Key.down, { from: length, to: length }, length, props);
				} else {
					this.onEnterBlock(e, range, pressed);
				};
			});

As the pressed button logic in /src/ts/lib/keyboard.ts > keyboard.shortcut shows, whenever Capslock is activated, the array of pressed buttons is appended with capslock, therefore the shortcut shown here isn't matched and causing the problem.

Suggesting Fix

Adding capslock+enter, capslock+shift+enter into keyboard.shortcut's matching string can fix this issue. However, it seems that this problem is just part of a broader set of related issues, so we should work toward a more universal fix instead of a one-off workaround.
