* feat(coding-agent): add fold/unfold to tree branch navigation
Remap left/right arrow keys in the session tree to jump between branch
segment starts (first child of each branching point). Left on a foldable
node (root or segment start) folds it, hiding its descendants. Right on
a folded node unfolds it. Nested fold state is preserved. Search and
filter changes reset all folds.
Folded branches show ⊞ in the connector (├⊞/└⊞) or as a prefix for
roots. Active path marker • appears after the fold indicator.
Add Page Up/Down support for paging through the tree list, consistent
with session selector and config selector.

Add configurable initial filter mode for the session tree navigator.
Users who always switch to a specific filter (e.g. no-tools via Ctrl+T)
can now set it as default in settings.
Same pattern as doubleEscapeAction (#404). Filter infra from #747.
* fix(coding-agent): tree selector focuses nearest visible ancestor
When the selected entry is not visible (filtered out by mode change or a
metadata entry like model_change), walk up the parent chain to find the
nearest visible ancestor instead of jumping to the last item.
Fixes selection behavior for:
- Initial selection when currentLeafId is a metadata entry
- Filter switching, e.g. Ctrl+U for user-only mode
* fix(coding-agent): tree selector preserves selection through empty filters
When switching to a filter with no results, e.g. labeled-only with no
labels and back, the cursor would reset to the first message instead of
the original selection.
Track lastSelectedId as a class member and only update it when
filteredNodes is non-empty, preserving the selection across empty filter
results.
* test(coding-agent): add tree selector filter and selection tests
- Test metadata entry handling (model_change, thinking_level_change)
- Test filter switching with parent traversal (default ↔ user-only)
- Test empty filter preservation (labeled-only with no labels)
Components with search inputs now implement Focusable interface and
propagate focus state to their child Input components. This allows
the hardware cursor to be positioned correctly for IME candidate
window placement.
Affected components:
- ModelSelectorComponent
- ScopedModelsSelectorComponent
- SessionSelectorComponent (and SessionList)
- ExtensionInputComponent
- LoginDialogComponent
- TreeSelectorComponent (and LabelInput)
fixes#827
* Add direct filter shortcuts for Tree mode
- Add Ctrl+D for default filter
- Add Ctrl+T for no-tools filter (toggles with default)
- Add Ctrl+U for user-only filter (toggles with default)
- Add Ctrl+L for labeled-only filter (toggles with default)
- Add Ctrl+A for all filter (toggles with default)
- Keep existing Ctrl+O / Shift+Ctrl+O cycle shortcuts
- Update help text to show new shortcuts
* simplify tree selector shortcut line
Follow-up to #717. Replaces all remaining hardcoded keybinding hints with configurable ones.
- Add pasteImage to AppAction so it can be configured in keybindings.json
- Create keybinding-hints.ts with reusable helper functions:
- editorKey(action) / appKey(keybindings, action) - get key display string
- keyHint(action, desc) / appKeyHint(kb, action, desc) / rawKeyHint(key, desc) - styled hints
- Export helpers from components/index.ts for extensions
- Update all components to use configured keybindings
- Remove now-unused getDisplayString() from KeybindingsManager and EditorKeybindingsManager
- Use keybindings.matches() instead of matchesKey() for pasteImage in custom-editor.ts
- Add selectedBg theme color for active line highlight
- Fix filter modes:
- no-tools: default minus tool results (still hides label/custom)
- user-only: just user messages
- labeled-only: just labeled entries
- all: everything
- Update theme.md with new color tokens (50 total)
- Check response.stopReason instead of catching errors for abort detection
- Return result object from _generateBranchSummary instead of throwing
- Fix summary attachment: attach to navigation target position, not old branch
- Support root-level summaries (parentId=null) in branchWithSummary
- Remove setTimeout hack for re-showing tree selector on abort
- Show ├─ for non-last siblings, └─ for last sibling
- Show │ gutter for descendants of non-last siblings
- Properly handle multiple roots display shift
- At indent 0: stay flat unless parent branches
- At indent 1: children go to indent 2 (visual grouping)
- At indent 2+: stay flat for single-child chains
- Remove gutter/connector complexity for now
- Only indent when parent has siblings (branch point)
- gutterLevels array tracks which levels need │ vs spaces
- connector: none/branch/last for ├─/└─ display
- Tool results show formatted call info like [read: path:1-10], [bash: cmd]
- Skip assistant messages with stopReason error/aborted
- Skip assistant messages with only tool calls (no text)
- Format built-in tools like tool-execution.ts (read, write, edit, bash, grep, find, ls)
- Custom tools show truncated JSON args
- Label editing with 'l' key
- Ctrl+O cycles through filters: default -> user-only -> labeled-only -> all
- Preserve cursor position when toggling filters
- Labels shown at front of node
- Normalize tabs/newlines in content
- extractContent limited to 200 chars for performance
- truncateToWidth on all rendered lines
- Iterative flattenTree to avoid stack overflow
- Linear chain optimization (no indent for single-child chains)
- Add TreeSelectorComponent with ASCII tree visualization
- Add AgentSession.navigateTree() for switching branches
- Add session_before_tree/session_tree hook events
- Add SessionManager.resetLeaf() for navigating to root
- Change leafId from string to string|null for consistency with parentId
- Support optional branch summarization when switching
- Update buildSessionContext() to handle null leafId
- Add /tree to slash commands in interactive mode
