Feat Request: Support custom filtering logic or a predicate function for ignoreInputs

[alt1o]

Currently, hotkeys supports the ignoreInputs option, which is great for preventing global shortcuts from triggering while typing. However, in many real-world scenarios, we need more granular control.

The Problem:

We are building a rich text editor where shortcuts (like Cmd+Z for undo) are registered globally on the document.

Scenario A: When a user is typing in the main editor body, we want Cmd+Z to trigger our custom undo logic.

Scenario B: If the user moves focus to a comment input or a sidebar text field, we want to ignore the global shortcut and let the browser's default input behavior take over.

Currently, if we set ignoreInputs: true, Scenario A fails. If we set it to false, Scenario B triggers the wrong undo logic.

The Proposal:

Allow ignoreInputs to accept a predicate function, or introduce a filter option. This would allow us to check the event target and decide whether to skip the shortcut based on the UI context.
