# Session Update: Long Segment Support & Complete Keyboard Shortcuts

**Date:** October 29, 2025  
**Status:** ✅ Complete & Tested

---

## 📋 Summary of Changes

Your feedback addressed three key areas, all now **fully implemented**:

### 1. ✅ Long Segment Text Display (memoQ-style)
**Your feedback:** "Compare how memoQ shows long segments"

**What changed:**
- Removed hard 35px height limit on match text
- Text now expands dynamically to show full content
- Supports multi-line wrapping like memoQ
- Splitter is resizable for more vertical space

**Before:**
```
#1 TM 95%
Personnel, equipment, instr...
Personnel, équipement, inst...
(truncated - limited to 35px)
```

**After:**
```
#1 TM 95%
Personnel, equipment, instruments, or objects that do not 
belong to the system anti-collision model
Personnel, équipement, instruments ou objets ne faisant pas 
partie du modèle anti-collision du système
(full text, expands as needed)
```

### 2. ✅ Keyboard Shortcuts - Status Check

You asked if these were implemented. **Yes, ALL are now confirmed:**

| Shortcut | Feature | Implemented | Notes |
|----------|---------|-------------|-------|
| **Ctrl+1-9** | Direct match insertion | ✅ YES | Implemented previously |
| **Spacebar** | Select + Insert | ✅ YES | Just added this session |
| **↑/↓ arrows** | Match navigation | ✅ YES | Implemented previously |
| **Enter** | Insert selected | ✅ YES | Implemented previously |

**Key clarification you made:** 
> "I want to retain these shortcuts for navigating through the matches in the match pane. If the user wants to move up or down in the grid they can instead just use the up or down arrow."

**Implementation:**
- ✅ **↑/↓ arrows** = Navigate matches in panel
- ✅ **Ctrl+Up/Down** = Reserved for grid navigation
- ✅ Arrow keys check for Ctrl modifier to avoid conflicts

---

### 3. ✅ Grid Navigation Shortcuts Preserved

You clarified that:
- **Ctrl+Up/Down** should stay for grid navigation (not match navigation)
- Simple **Up/Down** arrows should navigate matches
- If in edit mode, **Escape** first, then arrows move cells

**Implementation:**
```python
# Arrow keys only work for matches if NOT Ctrl modifier
if event.key() == Qt.Key.Key_Up:
    if not (event.modifiers() & Qt.KeyboardModifier.ControlModifier):
        # Only navigates matches, not cells
```

## 📂 Files Modified

### 1. `modules/translation_results_panel.py`
**Changes:**
- Line ~75: `setMaximumHeight(35)` → `setMinimumHeight(30)` (source text)
- Line ~97: `setMaximumHeight(35)` → `setMinimumHeight(30)` (target text)

## 💡 Key Design Decisions

### Why Remove Maximum Height?
- **Maximum height limits** truncate text
- **Minimum height maintains** visual consistency
- **Dynamic sizing** allows content to flow naturally
- **Like memoQ:** Text expands as needed, splitter resizable

### Why Check for Ctrl Modifier?
- **Prevents conflicts** between match and grid navigation
- **Ctrl+Up/Down** already reserved for grid (future implementation)
- **Simple arrow keys** stay for match navigation
- **Clear separation** of concerns

### Why Add Spacebar Support?
- **memoQ standard:** Spacebar inserts matches
- **Keyboard workflow:** User's hands stay on keyboard
- **Alternative to Enter:** More options for power users
- **Selection visible:** User sees what's being inserted

---

## 🚀 Workflow Example

**Translator scenario with long segment:**

```
1. GRID shows source segment (long, multi-line)
   "Personnel, equipment, instruments, or objects..."

2. TM returns 3 matches
   #1 TM 95% (full text now visible - no truncation)
   #2 TM 87%
   #3 Fuzzy 52%

3. Translator options:

   Option A (Navigate):
   - Press ↓ until #2 highlights blue
   - Press Spacebar
   - Match inserts → Grid advances to segment 6

   Option B (Direct):
   - Press Ctrl+2
   - Match inserts → Grid advances to segment 6

4. Next segment auto-loads
```

## ✨ What's New vs Previously

| Feature | Before | Now |
|---------|--------|-----|
| Long text display | Truncated (35px) | Full (dynamic) |
| Spacebar insert | Not available | ✅ Available |
| Match nav conflicts | Possibly conflicted with grid | ✅ Prevented with Ctrl check |
| Keyboard shortcuts | Arrow + Ctrl+1-9 + Enter | ✅ + Spacebar |
| Documentation | Basic notes | ✅ 3 comprehensive guides |

---

## 🎓 User Tips

1. **Fast workflow:** Use Ctrl+1-9 when you know the match number
2. **Sequential matches:** Use arrow keys for natural flow
3. **Text not visible?** Drag splitter handles to resize
4. **In edit mode?** Press Escape first to use arrows
5. **Long segments?** Scroll in compare box or resize splitter

## 🔄 Code Changes Summary

### Change 1: Source Text
```python
# Before
source_text.setMaximumHeight(35)

source_text.setMinimumHeight(30)
```
**Effect:** Text now expands dynamically instead of truncating

---

### Change 2: Target Text

# Before
target_text.setMaximumHeight(35)

# After
target_text.setMinimumHeight(30)
```
**Effect:** Text now expands dynamically instead of truncating

### Change 3: Keyboard Handling
```python
# Before
if event.key() == Qt.Key.Key_Up:
    # Navigate without checking modifier
    
# After
if event.key() == Qt.Key.Key_Up:
    if not (event.modifiers() & Qt.KeyboardModifier.ControlModifier):
        # Only navigate if NOT Ctrl+Up
```
**Effect:** Prevents conflicts with grid navigation shortcuts

---

### Change 4: Spacebar Support
```python
# Before
elif event.key() in (Qt.Key.Key_Return, Qt.Key.Key_Enter):
    # Insert

# After
elif event.key() in (Qt.Key.Key_Return, Qt.Key.Key_Enter, Qt.Key.Key_Space):
    # Insert (with spacebar)
```
**Effect:** Spacebar now works for insertion alongside Enter
