BINDINGS: list[BindingType] = [Binding(
'up',

'Up',
show=False,Key bindings for model navigation, selection, defaulting, and cancel.
Arrows move the cursor, Page Up/Down jump by a visual page, Tab copies
the highlighted spec into the filter input, Enter selects, Ctrl+S
toggles the default model, and Esc dismisses. All bindings use
priority=True so they take precedence over the embedded Input;
vim-style j/k bindings are deliberately omitted because they would
prevent typing those letters into the always-focused filter input.
