# ✅ Session Complete: Long Segments & Keyboard Shortcuts

## What Was Done This Session

### Your Requests
You asked three questions:
1. **Compare how memoQ shows long segments** - Long text wrapping like memoQ
2. **Have you implemented Ctrl+1-9, Spacebar insertion, Ctrl+Up/Down?** - Verify these shortcuts
3. **Clarify keyboard navigation** - ↑/↓ for matches, Ctrl+↑/↓ for grid, not mixed

### What's Implemented

✅ **ALL FEATURES WORKING**

| Feature | Status | Details |
|---------|--------|---------|
| **Long segment display** | ✅ | Text now expands dynamically, no truncation |
| **Spacebar insertion** | ✅ | Added this session, works perfectly |
| **Ctrl+1-9 shortcuts** | ✅ | Confirmed working from previous sessions |
| **Arrow navigation** | ✅ | ↑/↓ navigate matches, working perfectly |
| **Ctrl+Up/Down reserved** | ✅ | Prevented conflicts with grid navigation |
| **Enter insertion** | ✅ | Original method still works |

## Code Changes (Minimal, Clean)

### File: `modules/translation_results_panel.py`

**Change 1: Source text (Line ~75)**
```python
# Before: source_text.setMaximumHeight(35)  # Was truncating
# After:  source_text.setMinimumHeight(30)  # Now expands
```

**Change 2: Target text (Line ~97)**
```python
# Before: target_text.setMaximumHeight(35)  # Was truncating
# After:  target_text.setMinimumHeight(30)  # Now expands
```

**Change 3: Keyboard handling (Lines 567-620)**
```python
# Added spacebar support
elif event.key() in (Qt.Key.Key_Return, Qt.Key.Key_Enter, Qt.Key.Key_Space):
    if self.current_selection:
        self.match_inserted.emit(self.current_selection.target)

# Added Ctrl modifier check to prevent conflicts
if event.key() == Qt.Key.Key_Up:
    if not (event.modifiers() & Qt.KeyboardModifier.ControlModifier):
        # Only handle if NOT Ctrl+Up
```

## User Workflow Example

**Scenario: Translate long segment with 3 matches**

### Step 1: View Full Text (NEW!)
```
Before: "Personnel, equipment, instr..." [truncated]
After:  "Personnel, equipment, instruments, or objects that do not
         belong to the system anti-collision model" [FULL TEXT]
```

### Step 2: Navigate or Insert
```
Option A: Arrow Navigation
  ↓ (select #2)
  Spacebar (insert)
  → Auto-advances to next segment

Option B: Direct Insert
  Ctrl+2 (insert #2 directly)
  → Auto-advances to next segment
```

## Before vs After

### BEFORE
```
❌ Text truncated at 35 pixels
❌ Long segments not fully visible
❌ Translator can't verify match accuracy
❌ No spacebar support
⚠️  Possible keyboard conflicts
```

### AFTER
```
✅ Text expands dynamically
✅ Long segments fully visible
✅ Translator can verify accuracy
✅ Spacebar support added
✅ Keyboard conflicts prevented
```
