```

**Problems:**
- ❌ Text cut off mid-sentence
- ❌ Can't see full context
- ❌ Translator must guess completion
- ❌ Difficult to verify match accuracy
- ❌ Not professional quality

```

**Improvements:**

## Code Changes

### Change 1: Source Text Height

#### BEFORE
```python
source_text = QLabel(match.source)
source_text.setWordWrap(True)
source_text.setMaximumHeight(35)  # ← LIMITS TEXT TO 35 PIXELS
source_font = QFont()
source_font.setPointSize(8)
source_text.setFont(source_font)
source_layout.addWidget(source_text)
```

**Effect:** Text truncated at 35 pixels, multi-line text cut off

#### AFTER
```python
source_text = QLabel(match.source)
source_text.setWordWrap(True)
source_text.setMinimumHeight(30)  # ← ALLOWS EXPANSION ABOVE 30 PIXELS
source_font = QFont()
source_font.setPointSize(8)
source_text.setFont(source_font)
source_layout.addWidget(source_text)
```

**Effect:** Text expands dynamically, no maximum height limit

---

### Change 2: Target Text Height

#### BEFORE
```python
target_text = QLabel(match.target)
target_text.setWordWrap(True)
target_text.setMaximumHeight(35)  # ← LIMITS TEXT TO 35 PIXELS
target_font = QFont()
target_font.setPointSize(8)
target_text.setFont(target_font)
target_layout.addWidget(target_text)
```

**Effect:** Text truncated at 35 pixels, multi-line text cut off

#### AFTER
```python
target_text = QLabel(match.target)
target_text.setWordWrap(True)
target_text.setMinimumHeight(30)  # ← ALLOWS EXPANSION ABOVE 30 PIXELS
target_font = QFont()
target_font.setPointSize(8)
target_text.setFont(target_font)
target_layout.addWidget(target_text)
```

**Effect:** Text expands dynamically, no maximum height limit

## Keyboard Shortcuts: Before & After

### BEFORE: Limited Shortcuts
```
Shortcuts available:
  ↑/↓        Navigate matches
  Enter      Insert match
  Ctrl+1-9   Insert by number
  
Issues:
  ❌ No spacebar support
  ⚠️  Might conflict with grid Ctrl+Up/Down
  ⚠️  No documented conflict prevention
```

### AFTER: Complete Shortcuts with Conflict Prevention
```
Match Panel Shortcuts:
  ↑/↓        Navigate matches (checked: not Ctrl+modifier)
  Spacebar   Insert match (NEW!)
  Enter      Insert match
  Ctrl+1-9   Insert by number
  
Grid Shortcuts (Reserved):
  Ctrl+↑/↓   Grid navigation (NOT captured by matches)
  ↑/↓        Navigate grid cells (when not in match panel)
  Escape     Exit edit mode

Implementation:
  ✅ Ctrl modifier check prevents conflicts
  ✅ Clear separation of concerns
  ✅ Professional workflow
```

## Text Size Comparison

### Single-line Text (Before & After - No Change)

```
BEFORE:  #1 TM 95%
         Source text here
         Target text here
         (Fits in ~35px)

AFTER:   #1 TM 95%
         Source text here
         Target text here
         (Still ~35px, no wasted space)
```

### Multi-line Text (Before Truncated, After Full)

```
BEFORE:  #1 TM 95%
         Personnel, equipment, instr...  (CUT OFF!)
         Personnel, équipement, inst... (CUT OFF!)
         Height: 35px max
         
AFTER:   #1 TM 95%
         Personnel, equipment, instruments,
         or objects that do not belong to
         the system anti-collision model
         (Full text visible)
         Personnel, équipement, instruments
         ou objets ne faisant pas partie du
         modèle anti-collision du système
         (Full text visible)
         Height: Dynamic (80-120px as needed)
```

## User Experience Workflow

### BEFORE: Truncated Text Frustration
```
1. Translator sees long segment
   "Personnel, equipment, instruments..."
   
2. TM returns matches
   #1 matches but text is cut off
   #2 matches but text is cut off
   #3 might be better but can't see full text
   
3. Translator hesitates
   "Which match is best? I can't see the full text!"
   
4. Quality suffers
   "I'll just guess and move on..."
```

### AFTER: Professional Verification
```
1. Translator sees long segment (on left)
   
2. TM returns matches (on right)
   #1 shows full text - can verify accuracy
   #2 shows full text - can compare
   #3 shows full text - can choose best
   
3. Translator decides with confidence
   "This one is perfect - I can see it matches fully!"
   
4. Quality improves
   "I can verify every match before inserting"
```

```

### User Experience
```
memoQ:          Professional CAT tool quality
Supervertaler:  Professional CAT tool quality
Result:         ✅ Feature parity
```
