# Introduce focus stack to handle hotkeys
This PR introduces a focus stack to track the order in which the
elements are focused:
- Each focused element has a unique focus id
- When an element is focused, it is pushed on top of the stack
- When an element loses focus, we remove it from the stack
This focus stack is then used to determine which hotkeys are available.
The previous implementation lead to many regressions because of race
conditions, of wrong order of open and close operations and by
overwriting previous states. This implementation should be way more
robust than the previous one.
The new api can be incrementally implemented since it preserves
backwards compatibility by writing to the old hotkey scopes states.
For now, it has been implemented on the modal components.
To test this PR, verify that the shortcuts still work correctly,
especially for the modal components.
# Keyboard Navigation and Shortcuts Implementation on the board
This PR implements keyboard navigation and shortcuts for the Record
Board component, enabling users to navigate and interact with board
cards using keyboard inputs.
## Key changes
### Navigation Architecture
- Added `useBoardCardNavigation` hook for directional navigation (arrow
keys)
- Implemented scroll behavior to automatically focus visible cards
- Created card focus/active states with component-level management
### State Management
- Added new component states: `focusedBoardCardIndexesComponentState`,
`activeBoardCardIndexesComponentState`,
`isBoardCardActiveComponentFamilyState`
- Extended index tracking with column/row position indicators
- Create hooks to manage these states
### Hotkey Implementation
- Created new `RecordBoardHotkeyEffect` component for hotkey handling
- Added `BoardHotkeyScope`
- Implemented Escape key handling to clear selections
- Replaced table-specific `TableHotkeyScope` with more generic
`RecordIndexHotkeyScope`. This is because, before, the hotkey scope was
always set to Table inside the page change effect, and we used the table
hotkey scope for board shortcuts, which doesn't make a lot of sense.
Since we don't know upon navigation on which type of view we are
navigating, I introduced this generic hotkey scope which can be used on
the table and on the board.
### Page Navigation Integration
- Modified `PageChangeEffect` to handle both table and board view types
- Added cleanup for board state upon navigating away from record pages
### Component Updates
- Updated `RecordBoardColumn` to track indexes for position-based
navigation
- Added `RecordBoardScrollToFocusedCardEffect` for auto-scrolling to
focused cards
- Added `RecordBoardDeactivateBoardCardEffect` for cleanup
This implementation maintains feature parity with table row navigation
while accounting for the 2D navigation needs of the board view.
