 - **Insert:** type a case-insensitive substring to filter; arrow keys or Ctrl-J / Ctrl-K navigate matches; Enter browses the chosen categories; Esc returns to normal mode without clearing the filter. Space is ordinary input here.
 - Checkboxes select categories for browsing; the dimmed `p` suffix marks pins independently. Hidden checks survive filtering. Enter still browses checked categories when there are no visible matches; without checks, an empty result makes browsing a no-op. Pinning, renaming, and toggling require a visible selected row.
 
+### Category search
+
+Press `i` in a category or combined-category feed to search only its channels' histories—not just already loaded videos. Enter submits a changed query and returns to normal mode; an unchanged query keeps cached results and pagination. Clear the field and submit to restore the ordinary upload feed. Esc leaves the draft unsubmitted.
+
+Each category and combined feed retains its own draft, submitted query, results, and pagination independently of general Search. Subsequent pages use the same scoped query and shared 60-video budget. Empty categories and failed scoped requests never fall back to global search. Search input in other views still opens general YouTube Search.
+
+The direct Search and Feed jumps use the configurable `view.search` and `view.feed` actions. They preserve cached views and history, and do not run inside text inputs or selectors.

 ### Combined category feeds
 
 Check multiple categories in `c`, then press Enter to open their combined feed. One checked category opens its ordinary view; no checks retain the usual single-category shortcut. Esc discards the selector's staged choices. Reopening `c` from a combined feed prechecks its member categories.
 
-The combined feed uses the shared temporary tab, replacing the prior unpinned category/channel/collection view. Channels and video IDs are deduplicated, and videos use the same newest-first ordering and infinite scrolling as other feeds. Back/forward navigation restores cached rows, selection, and pagination.

The new flat category becomes active without automatic pinning or re-fetching matching cached pages. Its memberships are an independent copy, not links to the original categories.

 ## Loading and previews
 
-Search loads up to 60 results per page. Feed and category views share a **60-upload total request budget per load**, distributed fairly across active channels—not 60 per channel. Each channel retains its own offset; exhausted channels stop receiving requests, and feeds with more than 60 channels rotate through them across loads. Matching ranges are batched across at most four concurrent yt-dlp processes, with further batches queued. Individual channel views can use the full 60-row budget.
+General Search loads up to 60 results per page. Feed and category views, including scoped category searches, share a **60-video total request budget per load**, distributed fairly across active channels—not 60 per channel. Each channel retains its own offset; exhausted channels stop receiving requests, and feeds with more than 60 channels rotate through them across loads. Matching ranges are batched across at most four concurrent yt-dlp processes, with further batches queued. Individual channel views can use the full 60-row budget.
 
 In normal mode, forward video navigation authorizes prefetch when 20 loaded rows remain. Each successful page clears that intent, so short, duplicate-only, or unavailable batches do not immediately chain additional loads at startup. Only one page request runs at a time; insert mode and open popups pause automatic prefetch. A feed page is accepted only after every batch succeeds. Switching views cancels running and queued batches; returning resumes the same unaccepted per-channel ranges. Deep channel archives can get slower because yt-dlp offsets traverse earlier pages again.
