# tlcedit vs mcedit — Comprehensive Parity Assessment
|
||||
|
||||
**Created:** 2026-06-20
|
||||
**Source:** MC default keymap (`misc/mc.default.keymap` `[editor]` section) vs tlcedit `handlers.rs`
|
||||
**Goal:** Every keybinding in mcedit must match in tlcedit and provide the same action
|
||||
|
||||
---
|
||||
|
||||
## Executive Summary
|
||||
|
||||
**Overall parity: ~85%** (up from ~45% pre-P1, ~75% after P1+P2, after P1+P2+P3 implementation, 2026-06-20)
|
||||
|
||||
| Category | Count | Severity | Status |
|
||||
|----------|-------|----------|--------|
|
||||
| **Key conflicts** (same key, different action) | 0 | ~~🔴 CRITICAL~~ | ✅ All fixed (P1) |
|
||||
| **Wrong keys** (action exists, different key) | 0 | ~~🟡 HIGH~~ | ✅ All fixed (P1) |
|
||||
| **Missing actions** (no key, no implementation) | ~8 | 🟡 MEDIUM | P1/P2/P3 reduced from 22 |
|
||||
| **Correct matches** | ~65 | ✅ | Up from ~28 |
|
||||
|
||||
---
|
||||
|
||||
## CRITICAL: Key Conflicts
|
||||
|
||||
These bindings use the SAME key in both editors but perform DIFFERENT actions.
|
||||
These MUST be fixed first — they cause user confusion and data loss.
|
||||
|
||||
### C1: Ctrl-S — Save vs SyntaxOnOff
|
||||
|
||||
| Editor | Key | Action |
|
||||
|--------|-----|--------|
|
||||
| mcedit | `Ctrl-S` | Toggle syntax highlighting on/off |
|
||||
| tlcedit | `Ctrl-S` | **Save file** (also F2) |
|
||||
|
||||
**Problem:** A user pressing Ctrl-S expecting syntax toggle will unexpectedly save.
|
||||
**Fix:** tlcedit should use Ctrl-S for SyntaxOnOff. Save is already on F2 (correct).
|
||||
**Impact:** Remove Ctrl-S as a save shortcut in the editor dispatcher.
|
||||
|
||||
### C2: Ctrl-Y — DeleteLine vs Redo
|
||||
|
||||
| Editor | Key | Action |
|
||||
|--------|-----|--------|
|
||||
| mcedit | `Ctrl-Y` | Delete current line |
|
||||
| tlcedit | `Ctrl-Y` | **Redo** |
|
||||
|
||||
**Problem:** Redo on Ctrl-Y is a Windows/VSCode convention, not MC.
|
||||
**Fix:** Move redo to `Alt-R` (MC's key). Implement DeleteLine on Ctrl-Y.
|
||||
**Impact:** Add `delete_line()` to buffer; rewire handlers.
|
||||
|
||||
### C3: Ctrl-P — SpellCheck vs Macro Playback
|
||||
|
||||
| Editor | Key | Action |
|
||||
|--------|-----|--------|
|
||||
| mcedit | `Ctrl-P` | Spell check current word |
|
||||
| tlcedit | `Ctrl-P` | **Play macro** |
|
||||
|
||||
**Problem:** Macro playback on Ctrl-P conflicts with MC spell check.
|
||||
**Fix:** MC doesn't have a dedicated macro playback key — macros in MC use
|
||||
`Ctrl-R` to start/stop recording and then numeric keys (Ctrl-0..9) to replay.
|
||||
Move macro playback to a different binding.
|
||||
**Impact:** Change macro system.
|
||||
|
||||
### C4: Ctrl-L — Refresh vs Relative Line Numbers
|
||||
|
||||
| Editor | Key | Action |
|
||||
|--------|-----|--------|
|
||||
| mcedit | `Ctrl-L` | Refresh screen (redraw) |
|
||||
| tlcedit | `Ctrl-L` | **Toggle relative line numbers** |
|
||||
|
||||
**Problem:** Relative line numbers is a TLC addition not in MC.
|
||||
**Fix:** Move relative line toggle to `Alt-N` (MC's ShowNumbers key).
|
||||
Ctrl-L should trigger a screen refresh.
|
||||
**Impact:** Minor — rewire two bindings.
|
||||
|
||||
### C5: Ctrl-Z — Undo vs WordLeft Alias
|
||||
|
||||
| Editor | Key | Action |
|
||||
|--------|-----|--------|
|
||||
| mcedit | `Ctrl-Z` | Move cursor one word left (alias for Ctrl-Left) |
|
||||
| tlcedit | `Ctrl-Z` | **Undo** |
|
||||
|
||||
**Problem:** Undo on Ctrl-Z is standard everywhere EXCEPT MC.
|
||||
**Decision needed:** Do we match MC exactly, or keep the universal Ctrl-Z=Undo?
|
||||
**Recommendation:** Keep Ctrl-Z as Undo (it's a universal convention that even MC
|
||||
users expect in modern contexts). Document the deviation.
|
||||
|
||||
---
|
||||
|
||||
## HIGH: Wrong Keys (Action Exists, Different Key)
|
||||
|
||||
These actions exist in tlcedit but are triggered by a different key than MC expects.
|
||||
|
||||
### W1: Search — F7 vs Alt-F
|
||||
|
||||
| Editor | Key | Action |
|
||||
|--------|-----|--------|
|
||||
| mcedit | `F7` | Open search dialog |
|
||||
| tlcedit | `Alt-F` | Open search prompt |
|
||||
|
||||
**Fix:** Add F7 as primary search key. Keep Alt-F as alias.
|
||||
**Also:** `F17` for search-continue (repeat last search).
|
||||
|
||||
### W2: Replace — F4 vs Alt-%
|
||||
|
||||
| Editor | Key | Action |
|
||||
|--------|-----|--------|
|
||||
| mcedit | `F4` | Open replace dialog |
|
||||
| tlcedit | `Alt-%` (Alt-Shift-5) | Open replace prompt |
|
||||
|
||||
**Problem:** F4 in tlcedit currently has no binding in the editor.
|
||||
**Fix:** Map F4 to Replace. Keep Alt-% as alias.
|
||||
**Also:** `F14` for replace-continue.
|
||||
|
||||
### W3: SaveAs — F12 vs Shift-F2
|
||||
|
||||
| Editor | Key | Action |
|
||||
|--------|-----|--------|
|
||||
| mcedit | `F12` or `Ctrl-F2` | Save As |
|
||||
| tlcedit | `Shift-F2` | Save As |
|
||||
|
||||
**Fix:** Add F12 as primary SaveAs key. Keep Shift-F2 as alias.
|
||||
|
||||
### W4: Undo — Ctrl-U vs Ctrl-Z
|
||||
|
||||
| Editor | Key | Action |
|
||||
|--------|-----|--------|
|
||||
| mcedit | `Ctrl-U` | Undo |
|
||||
| tlcedit | `Ctrl-Z` | Undo |
|
||||
|
||||
**Fix:** Add Ctrl-U as MC-compatible undo key. Keep Ctrl-Z as modern alias.
|
||||
|
||||
### W5: Redo — Alt-R vs Ctrl-Y
|
||||
|
||||
| Editor | Key | Action |
|
||||
|--------|-----|--------|
|
||||
| mcedit | `Alt-R` | Redo |
|
||||
| tlcedit | `Ctrl-Y` | Redo |
|
||||
|
||||
**Fix:** Move redo to Alt-R (matching MC). Free up Ctrl-Y for DeleteLine.
|
||||
Keep Ctrl-Y as secondary alias for transition.
|
||||
|
||||
### W6: Bookmark — Alt-K vs Alt-M
|
||||
|
||||
| Editor | Key | Action |
|
||||
|--------|-----|--------|
|
||||
| mcedit | `Alt-K` | Set bookmark at cursor |
|
||||
| tlcedit | `Alt-M` | Set bookmark (BookmarkSet prompt) |
|
||||
|
||||
**Fix:** Change BookmarkSet trigger from Alt-M to Alt-K. Free up Alt-M.
|
||||
**Also:** Alt-O for BookmarkFlush (clear all), Alt-I for BookmarkPrev.
|
||||

## Improvement Plan
|
||||
|
||||
### Phase P1: Fix Critical Conflicts + High-Priority Missing ✅ COMPLETE (2026-06-20)
|
||||
|
||||
**Objective:** Eliminate key conflicts and add the most common missing actions.
|
||||
|
||||
#### Step 1: Fix Key Conflicts
|
||||
|
||||
1. **Ctrl-S → SyntaxOnOff** (remove Save shortcut; F2 remains)
|
||||
2. **Ctrl-Y → DeleteLine** (move Redo to Alt-R)
|
||||
3. **Ctrl-P → SpellCheckCurrentWord placeholder** (move macro playback)
|
||||
4. **Ctrl-L → Screen Refresh** (move relative-lines to Alt-N)
|
||||
5. **Ctrl-U → Undo** (add as alias for Ctrl-Z)
|
||||
6. **Macro playback → Ctrl-0..9** (MC-style: Ctrl-R records, Ctrl-0 replays)
|
||||
|
||||
**Files to modify:**
|
||||
- `src/editor/handlers.rs` — rewire all conflict bindings
|
||||
- `src/editor/macro.rs` — new numeric-key macro system
|
||||
|
||||
#### Step 2: Add Missing High-Priority Actions
|
||||
|
||||
1. **DeleteLine** (`Ctrl-Y`) — `buffer.delete_line()`
|
||||
2. **DeleteToEnd** (`Ctrl-K`) — delete from cursor to EOL
|
||||
3. **DeleteToWordBegin** (`Alt-Backspace`) — delete word backward
|
||||
4. **DeleteToWordEnd** (`Alt-D`) — delete word forward
|
||||
5. **ScrollUp/ScrollDown** (`Ctrl-Up`/`Ctrl-Down`) — viewport scroll without cursor move
|
||||
6. **TopOnScreen/BottomOnScreen** (`Ctrl-PgUp`/`Ctrl-PgDn`)
|
||||
7. **Shell** (`Ctrl-O`) — subshell from editor (already exists in filemanager)
|
||||
8. **Store/Cut** (`Ctrl-Insert`/`Shift-Delete`) — MC-style clipboard
|
||||
|
||||
**Files to modify:**
|
||||
- `src/editor/buffer.rs` — add `delete_line()`, `delete_to_end_of_line()`
|
||||
- `src/editor/cursor.rs` — add `delete_word_backward()`, `delete_word_forward()`
|
||||
- `src/editor/handlers.rs` — add new key bindings
|
||||
- `src/editor/view.rs` — add `scroll_up()`/`scroll_down()` (viewport-only)
|
||||
|
||||
#### Step 3: Fix Wrong Keys (add MC-primary aliases)
|
||||
|
||||
1. **F7 → Search** (keep Alt-F as alias)
|
||||
2. **F4 → Replace** (keep Alt-% as alias)
|
||||
3. **F12 → SaveAs** (keep Shift-F2 as alias)
|
||||
4. **F17 → SearchContinue** (repeat last search)
|
||||
5. **F14 → ReplaceContinue** (repeat last replace)
|
||||
6. **Alt-R → Redo** (keep Ctrl-Y as secondary during transition)
|
||||
7. **Alt-K → Bookmark** set (keep Alt-M during transition)
|
||||
8. **Alt-O → BookmarkFlush** (clear all bookmarks)
|
||||
9. **Alt-I → BookmarkPrev** (previous bookmark)
|
||||
10. **Alt-N → ShowNumbers** (toggle line numbers)
|
||||
|
||||
**Files to modify:**
|
||||
- `src/editor/handlers.rs` — add all F-key and Alt-key aliases
|
||||
|
||||
#### Step 4: Add Missing Selection Keys
|
||||
|
||||
1. **Shift-PgUp / Shift-PgDn** — select page up/down
|
||||
2. **Ctrl-Shift-Left / Ctrl-Shift-Right** — select word
|
||||
3. **Ctrl-Shift-Home / Ctrl-Shift-End** — select to file start/end
|
||||
|
||||
**Files to modify:**
|
||||
- `src/editor/cursor.rs` — add `select_page_up()`, `select_page_down()`
|
||||
- `src/editor/handlers.rs` — add shift+page and ctrl+shift+arrow bindings
|
||||
|
||||
### Phase P2: Viewer Parity ✅ COMPLETE (2026-06-20)
|
||||
|
||||
1. Add F5/F7 for goto/search in viewer
|
||||
2. Add `?` backward search
|
||||
3. Add Ctrl-S/Ctrl-R for search direction continue
|
||||
4. Add vim movement keys (h/j/k/l) in viewer
|
||||
5. Add Space/`f` for page down, `b`/Backspace for page up
|
||||
6. Add `g`/`Shift-G` for top/bottom
|
||||
7. Add Ctrl-A/Ctrl-E for Home/End
|
||||
8. Add `m`/`r` for viewer bookmarks
|
||||
|
||||
**Files to modify:**
|
||||
- `src/viewer/mod.rs` — expand key handler
|
||||
- `src/viewer/search.rs` — add backward search
|
||||
|
||||
### Phase P3: Editor Feature Gaps ✅ COMPLETE (2026-06-20)
|
||||
|
||||
**Done:**
|
||||
- ✅ F15 InsertFile — insert file contents at cursor
|
||||
- ✅ Insert/overwrite toggle — Insert key toggles mode, [OVR] shown in status bar
|
||||
- ✅ Ctrl-Q InsertLiteral — insert next key literally
|
||||
- ✅ Shift-Enter — insert newline above current line
|
||||
- ✅ F1 Help — built-in keybinding reference dialog (6 categories, 30+ bindings)
|
||||
- ✅ F8 MagicMode in viewer — auto-detect binary vs text via magic::detect_mode
|
||||
|
||||
**Deferred P3 items (require significant infrastructure):**
|
||||
1. **F9 Menu** — editor command menu (needs standalone menu system, separate from filemanager)
|
||||
2. **F11 UserMenu** — user-defined command menu (needs INI parser integration in editor context)
|
||||
3. **Alt-Enter Find** — quick file find (needs file manager integration)
|
||||
4. **Alt-Minus/Alt-Plus** — file history navigation (needs multi-file tab support)
|
||||
|
||||
### Phase P4: Advanced Features (future)
|
||||
|
||||
1. **Column selection mode** (F13) — block/column selection
|
||||
2. **Spell check** (Ctrl-P) — integrate spell checker
|
||||
3. **Block shift** — indent/outdent selected block
|
||||
4. **Paragraph up/down** — move by paragraph
|
||||
5. **Window management** — multi-file tabs, split, fullscreen
|
