+# Markdown Viewer/Editor — Integration Tests To Create
+
+## Keyboard Shortcut Forwarding
+- [x] Ctrl+S in edit mode triggers Phoenix save (not consumed by md editor)
+- [ ] Ctrl+P in edit mode opens Quick Open
+- [x] Ctrl+Shift+F in edit mode opens Find in Files
+- [x] Ctrl+B/I/U in edit mode applies bold/italic/underline (not forwarded)
+- [x] Ctrl+K in edit mode opens link input (not forwarded)
+- [x] Ctrl+Shift+X in edit mode applies strikethrough (not forwarded)
+- [x] Ctrl+Z/Y/Shift+Z in edit mode triggers undo/redo via CM (routed through Phoenix undo stack)
+- [x] Ctrl+A in edit mode selects all text natively (C/V/X not testable due to browser security)
+- [x] Escape in edit mode sends focus back to Phoenix editor
+- [x] F-key shortcuts (e.g. F8 for live preview toggle) work in edit mode
+- [x] F-key shortcuts work in reader mode
+
+## Document Cache & File Switching
+- [ ] Switching between two MD files is instant (no re-render, DOM cached)
+- [ ] Scroll position preserved per-document on switch
+- [ ] Edit/reader mode preserved globally across file switches
+- [ ] Switching MD → HTML → MD reuses persistent md iframe (no reload)
+- [ ] Closing live preview panel and reopening preserves md iframe and cache
+- [ ] Project switch clears all cached documents but preserves edit/reader mode
+- [ ] Edit mode persists when switching projects (was in edit → open new project md → still edit)
+- [ ] Working set changes sync to iframe (files removed from working set go to LRU)
+- [ ] LRU cache evicts beyond 20 non-working-set files
+- [ ] Reload button (in LP toolbar) re-renders current file, preserves scroll and edit mode
+
+## Selection Sync (Bidirectional)
+- [ ] Selecting text in CM highlights corresponding block in md viewer
+- [ ] Selecting text in md viewer selects corresponding text in CM
+- [ ] Clicking in md viewer (no selection) clears CM selection
+- [ ] Clicking in CM clears md viewer highlight
+- [ ] Selection sync respects cursor sync toggle (disabled when sync off)
+
+## Cursor/Scroll Sync
+- [ ] Clicking in CM scrolls md viewer to corresponding element
+- [ ] Clicking in md viewer scrolls CM to corresponding line (centered)
+- [ ] Cursor sync toggle button disables/enables bidirectional sync
+- [ ] Cursor sync toggle state preserved across toolbar re-renders (file switch, mode toggle)
+- [ ] Content sync still works when cursor sync is disabled
+- [ ] Cursor sync toggle works in both reader and edit mode
+- [ ] Disabling cursor sync in reader mode prevents CM scroll on click
+- [ ] Cursor sync works on newly edited elements after edit→reader switch
+- [ ] Edit→reader switch re-renders from CM content (data-source-line attrs refreshed)
+- [ ] Switching MD files preserves current edit/reader mode
+- [ ] Edit mode not reset when switching between MD files
+
+## Edit Mode & Entitlement Gating
+- [ ] Free user sees Edit button → clicking shows upsell dialog
+- [ ] Pro user sees Edit button → clicking enters edit mode
+- [ ] Entitlement change (free→pro) switches to edit mode automatically
+- [ ] Entitlement change (pro→free) switches to reader mode automatically
+- [ ] Edit/Reader toggle works correctly in the iframe toolbar
+
+## Toolbar & UI
+- [ ] Phoenix play button and mode dropdown hidden for MD files
+- [ ] Phoenix play button and mode dropdown visible for HTML files
+- [ ] Phoenix play button and mode dropdown visible for custom server MD files
+- [ ] Progressive toolbar collapse: blocks collapse first, then lists, then text formatting
+- [ ] Toolbar collapse thresholds work at various widths
+- [ ] Dropdown menus in collapsed toolbar open and close correctly
+- [ ] Format buttons apply formatting and close dropdown
+- [ ] Tooltip delay is 800ms (not too aggressive)
+- [ ] Underline button has shortcut in tooltip (Ctrl+U / ⌘U)
+- [ ] Reader button has book-open icon and "Switch to reader mode" title
+- [ ] Edit button has pencil icon and "Switch to edit mode" title
+- [ ] 1px white line at bottom of preview not visible (box-sizing: border-box on toolbar)
+
+## Checkbox (Task List) Sync
+- [ ] Clicking checkbox in edit mode toggles it and syncs to CM source ([x] ↔ [ ])
+- [ ] Checkboxes enabled in edit mode, disabled in reader mode
+- [ ] Checkbox toggle creates an undo entry
+- [ ] Undo reverses checkbox toggle
+
+## Format Bar & Link Popover
+- [ ] Format bar appears on text selection (single line, not wrapping)
+- [ ] Format bar includes underline button
+- [ ] Format bar dismissed on scroll
+- [ ] Link popover appears when clicking a link in edit mode
+- [ ] Link popover URL opens in default browser (not Electron window)
+- [ ] Link popover dismissed on scroll
+- [ ] Escape in link popover only dismisses popover, refocuses editor
+- [ ] Escape in slash menu only dismisses menu, refocuses editor
+- [ ] Escape in lang picker only dismisses picker, refocuses editor
+
+## Empty Line Placeholder
+- [ ] Empty paragraph in edit mode shows "Type / for commands" hint text
+- [ ] Hint disappears as soon as user types
+- [ ] Hint only shows in edit mode, not reader mode
+- [ ] Hint shows on paragraphs with only a `<br>` child
+
+## Slash Menu (/ command)
+- [ ] Slash menu appears at the / cursor position (not at top of page)
+- [ ] Slash menu opens below cursor when space available
+- [ ] Slash menu opens above cursor when near bottom of viewport
+- [ ] Slash menu has gap between cursor line and menu (not overlapping)
+- [ ] Typing after / filters the menu items (e.g. /h1 shows Heading 1)
+- [ ] Arrow down/up scrolls selected item into view when outside viewport
+- [ ] Escape dismisses slash menu without forwarding to Phoenix
+- [ ] Escape refocuses the md editor after dismissing slash menu
+- [ ] Selected item wraps around (last → first, first → last)
+- [ ] Slash menu works at bottom of a long scrolled document
+
+## Keyboard Shortcut Focus
+- [ ] Ctrl+S saves file and keeps focus in md editor (not CM)
+- [ ] Forwarded shortcuts refocus md editor after Phoenix handles them
+
+## Code Block Editing
+- [ ] ArrowDown on last line of code block exits to paragraph below
+- [ ] ArrowDown on last line creates new `<p>` if none exists below
+- [ ] ArrowDown on last line moves to existing next sibling if present
+- [ ] ArrowDown on non-last line navigates normally within code block
+- [ ] Shift+Enter on last line of code block exits to paragraph below
+- [ ] Shift+Enter on non-last line does NOT exit (normal behavior)
+- [ ] Enter inside code block creates new line (not exit)
+- [ ] Code block exit syncs new paragraph to CM source
+- [ ] Intermediate code blocks: Shift+Enter exits on last line
+- [ ] Last code block in document: ArrowDown creates `<p>` and exits
+
+## Table Editing
+- [ ] Clearing a table cell with backspace produces valid markdown (no broken pipe rows)
+- [ ] Empty table cell renders as `|  |` in markdown source
+- [ ] Table cell with `<br>` only-child is treated as empty (br stripped before conversion)
+- [ ] Table cell with actual content + `<br>` preserves the line break
+- [ ] Tab navigation between table cells works
+- [ ] Adding new row via Tab at last cell works
+- [ ] Delete row / delete column via context menu works and syncs to CM
+- [ ] Table header editing syncs correctly to CM
+- [ ] Enter key blocked in table cells (no paragraph/line break insertion)
+- [ ] Shift+Enter blocked in table cells
+- [ ] Block-level format buttons hidden when cursor is in table (quote, hr, table, codeblock, lists)
+- [ ] Block type selector (Paragraph/H1/H2/H3) hidden when cursor is in table
+- [ ] Dropdown groups for lists and blocks hidden when cursor is in table
+- [ ] Pasting multi-line text in table cell converts to single line (newlines → spaces)
+- [ ] Moving cursor out of table restores all toolbar buttons
+- [ ] ArrowRight at end of last cell exits table to paragraph below
+- [ ] ArrowDown from last cell exits table to paragraph below
+- [ ] Enter in last cell exits table to paragraph below
+- [ ] If no paragraph exists below table, one is created on exit
+- [ ] If paragraph exists below table, cursor moves into it (no duplicate)
+- [ ] Cursor in table wrapper gap (outside cells) + Enter exits table
+- [ ] Cursor in table wrapper gap (outside cells) + typing is blocked
+- [ ] Table rows don't visually expand when cursor is in wrapper gap
+- [ ] "Delete table" option appears in table right-click context menu
+- [ ] "Delete table" option appears in row handle menu
+- [ ] "Delete table" option appears in column handle menu
+- [ ] Deleting table removes entire table-wrapper from DOM
+- [ ] Deleting table places cursor in next sibling element
+- [ ] Deleting table at end of document creates new empty paragraph
+- [ ] Deleting table syncs removal to CM source
+- [ ] Deleting table creates undo entry (Ctrl+Z restores table)
+- [ ] Add-column button (+) has visible dashed border matching add-row button style
+- [ ] Add-column button visible when table is active (cursor inside)
+
+## List Editing
+- [ ] Enter in a list item splits content at cursor into two `<li>` elements
+- [ ] Enter on empty list item exits list and creates paragraph below
+- [ ] Shift+Enter in list item inserts `<br>` (line break within same bullet)
+- [ ] Tab in list item indents it (nests inside sub-list under previous sibling)
+- [ ] Shift+Tab in list item outdents it to parent level
+- [ ] Shift+Tab outdent preserves trailing siblings as sub-list of moved item
+- [ ] Tab at first list item (no previous sibling) does nothing
+- [ ] Cursor position preserved after Tab indent
+- [ ] Cursor position preserved after Shift+Tab outdent
+- [ ] Enter in list creates proper `<li>` that syncs to markdown `- ` or `1. ` in CM
+- [ ] Nested list indentation syncs correctly to markdown (2 or 4 space indent)
+
+## UL/OL Toggle (List Type Switching)
+- [ ] Clicking UL button when in OL switches nearest parent list to `<ul>`
+- [ ] Clicking OL button when in UL switches nearest parent list to `<ol>`
+- [ ] UL/OL toggle only affects nearest parent list (not all ancestor lists)
+- [ ] UL/OL toggle preserves list content and nesting
+- [ ] UL/OL toggle syncs to CM (e.g. `1. item` → `- item`)
+- [ ] Toolbar UL button shows active state when cursor is in UL
+- [ ] Toolbar OL button shows active state when cursor is in OL
+- [ ] Block-level buttons (quote, hr, table, codeblock) hidden when cursor is in list
+- [ ] Block type selector (Paragraph/H1/H2/H3) hidden when cursor is in list
+- [ ] List buttons remain visible when cursor is in list (for UL/OL switching)
+- [ ] Moving cursor out of list restores all toolbar buttons
+
+## Image Handling
+- [ ] Images not reloaded when editing text in CM (DOM nodes preserved)
+- [ ] GIFs don't blink/restart when editing text elsewhere
+- [ ] Image upload placeholder (uploading.svg) is not preserved across updates
+- [ ] End key near image goes to end of current block (not end of file) on Win/Linux
+- [ ] Home key near image goes to start of current block (not start of file) on Win/Linux
+- [ ] Cmd+Right near image goes to end of block on Mac
+- [ ] Cmd+Left near image goes to start of block on Mac
+- [ ] End/Home work normally on lines without images
+
+## Heading Editing
+- [ ] Enter at start of heading (|Heading) inserts empty `<p>` above, heading shifts down
+- [ ] Enter in middle of heading splits: text before stays heading, text after becomes `<p>`
+- [ ] Enter at end of heading creates new empty `<p>` below (no content split)
+- [ ] Enter in middle syncs correctly to CM (heading line + new paragraph line)
+- [ ] Shift+Enter in heading creates empty `<p>` below without moving content
+- [ ] Shift+Enter moves cursor to new `<p>`, heading text untouched
+- [ ] Backspace at start of heading converts heading to `<p>` (strips ### prefix in CM)
+- [ ] Backspace at start of heading preserves content and cursor position
+- [ ] Backspace at start of heading updates toolbar from "Heading N" to "Paragraph"
+- [ ] Heading-to-paragraph conversion syncs correctly to CM source
+- [ ] Backspace in middle of heading works normally (deletes character)
+
+## Undo/Redo
+- [ ] Ctrl+Z undoes change in both md editor and CM (single undo stack)
+- [ ] Ctrl+Shift+Z / Ctrl+Y redoes change in both
+- [ ] Cursor restored to correct block element (source-line) after undo
+- [ ] Cursor restored to correct offset within block after undo
+- [ ] Undo/redo cursor works when editing at different positions in document
+- [ ] Typing in CM and undoing in CM doesn't interfere with md editor
+- [ ] Multiple rapid edits can be undone one by one
+
+## Scroll Behavior
+- [ ] Cursor sync scroll is instant (not smooth animated)
+- [ ] Scroll restore on file switch uses exact pixel position (no jump)
+- [ ] Scroll restore on reload uses source-line-based positioning
+- [ ] No progressive scroll-down on reload with many images (source-line approach)
+
+## Border & Styling
+- [ ] Subtle bottom border on #mainNavBar (rgba(255,255,255,0.08))
+- [ ] Subtle bottom border on #live-preview-plugin-toolbar (rgba(255,255,255,0.08))
+- [ ] No medium-zoom magnifying glass cursor on images
+- [ ] Cursor sync icon is subtle (secondary text color, not accent blue)
+
+## Translation (i18n)
+- [ ] en.json strings load correctly (toolbar.reader, format.underline, etc.)
+- [ ] Locale with region code (e.g. en-GB) falls back to base (en) if specific file missing
+- [ ] No "Failed to load locale" console warnings for valid locales
+- [ ] gulp translateStrings translates both Phoenix NLS and mdviewer locales
+- [ ] Translated locale files copied back to src-mdviewer/src/locales/
+
+## In-Document Search (Ctrl+F)
+- [ ] Ctrl+F opens search bar in md viewer (both edit and reader mode)
+- [ ] Ctrl+F with text selected pre-fills search and highlights closest match as active
+- [ ] Typing in search input highlights matches with debounce (300ms)
+- [ ] Match count shows "N/total" format
+- [ ] Enter / Arrow Down navigates to next match
+- [ ] Shift+Enter / Arrow Up navigates to previous match
+- [ ] Navigation wraps around (last → first, first → last)
+- [ ] Active match scrolls into view (instant, centered)
+- [ ] Escape closes search bar and restores cursor to previous position
+- [ ] Escape in search does NOT forward to Phoenix (no focus steal)
+- [ ] Closing search clears all mark.js highlights
+- [ ] Search works across cached document DOMs (uses #viewer-content)
+- [ ] × button closes search
+- [ ] Search starts from 1 character
+- [ ] Switching documents with search open re-runs search on new document
+- [ ] Switching back to previous document restores search match index (e.g. was on 3/5, returns to 3/5)
