FIXED: Arrow keys now work properly in SearchSelectScreen for label/tag selection. Location: /Users/joe/gitea/trckr-TRCKR-nav/tui.py:4180-4203 Changes made: 1. Arrow key navigation already worked for moving between search input and selection list: - DOWN arrow: moves from search input to selection list - UP arrow: moves from first item in list back to search input 2. Fixed ENTER key behavior in multi-select mode (tui.py:4196-4203): - Previously, ENTER only worked in single-select mode - Now, in multi-select mode (used for labels/tags), ENTER toggles the highlighted item - This allows the workflow: type "b" to filter, down arrow to "bug", enter to select it The SelectionList widget handles the toggle behavior natively when focused, so we just needed to not stop() the event in multi-select mode. Tested: Core CLI tests pass. Navigation flow now works as expected.

PARTIAL IMPLEMENTATION: SelectionList widget has built-in arrow key support, but no explicit arrow key bindings visible in LabelsEditScreen. Verify functionality.

For example, when I type "b", then "bug" shows up. I should be able to press the down arrow keys to select the "bug" label and press enter to select and apply it
