 ## Application actions and uninstall
 
-Select an application and open **Actions ⌘K**. The red **Uninstall application** action opens a review sheet with file checkboxes, paths, sizes, and a selected-item count. Filtering by name or path does not change selections. Up/Down highlights rows; Space toggles the highlighted eligible item when the file list has focus. Back or Escape returns to the launcher. Return or the uninstall button opens a final confirmation; nothing is moved merely by choosing the action.
+Select an application and open **Actions ⌘K**. **Open** is the first, default-selected action and uses the same launch path, successful-launch history tracking, dismissal, and error reporting as Return in the application list. Filtering resets selection to the first matching action; an empty result does nothing on Return. Up/Down or Control-K/Control-J navigates actions without changing the selected application.
 
-The actions selector is an arrowless panel inside the launcher, aligned to the bottom and right edges of the footer action pill, replacing it visually while open rather than floating above it. It shares the launcher's frosted Sunset background, 38-point selection row height, 22×22-point icon boxes with 12-point icon-to-text spacing, 14-point action and search text, rounded selection styling, and Return key badge; selection width follows the panel. Application and command rows use the same sizing constants. SF Symbol optical alignment insets are removed so command icons render inside the same bounds as application icons. The application name appears at the top and borderless action search sits eight points from the bottom, without a divider. Native animations crossfade the panel and footer pill: 160 milliseconds to open and 120 milliseconds to close, with unchanged geometry. Reduce Motion disables the animation. Rapid reopening invalidates stale dismissal completions, and closing panels immediately stop intercepting input. Escape, Command-K, an outside click, or switching away closes it and restores the pill. Closing while Conjure remains active restores launcher search focus; switching away does not steal focus back. Return in action search chooses the visible action rather than launching the underlying application.

 Discovery includes the application bundle and exact bundle-ID paths in your Library: Preferences, Caches, Application Support, Logs, Saved Application State, Application Scripts, and Containers. Embedded extension identifiers are included. App-group entitlements are read from validated native code signatures; related shared Group Containers and Application Scripts remain unchecked because other applications may use them. Conjure does not guess name-based leftovers or include package receipts. This is conservative discovery, not a guarantee that every associated file is found.
