## Real-World Use Cases

179
-
### Keyboard Shortcuts
138
+
### Use Case 1: Building a Function from Scratch
180
139
181
-
Make Copilot workflows faster:
140
+
You're starting a new function to parse CSV files. Instead of typing everything manually:
182
141
183
-
| Action | Windows/Linux | macOS |
184
-
|--------|------------------|-------|
185
-
| Accept Suggestion |`Tab`|`Tab`|
186
-
| Dismiss Suggestion |`Escape`|`Escape`|
187
-
| Request Suggestion |`Alt + \`|`⌥ \`|
188
-
| Open Copilot Chat | Click icon or `Ctrl + Alt + I`|`⌘ ⌥ I`|
142
+
1. Write a descriptive comment:
143
+
```python
144
+
# Function to parse a CSV file and return a list of dictionaries
145
+
defparse_csv(file_path):
146
+
```

### Writing Better Comments for Copilot
148
+
2. Copilot suggests the implementation
149
+
3. Review the suggestion, accept it with `Tab`, and move forward
191
150
192

Copilot's suggestions improve with clear context. Here's how:

### Use Case 2: Refactoring Legacy Code
193
152
194
-
**❌ Vague:**
195
-
```javascript
196
-
// process data
197
-
functionprocess(data) {
198
-
```
199
-
200
-
**✅ Clear:**
201
-
```javascript
202
-
// Filter array to include only items with quantity > 0, then sort by price ascending
203
-
functionfilterAndSortByPrice(products) {
204
-
```
205
-
206
-
With the second approach, Copilot generates more accurate code.
153
+
You have a messy function that needs improvement:

## Common Use Cases
209
-
210
-
### Use Case 1: Boilerplate Code
211
-
212
-
Instead of typing repetitive code, let Copilot do the heavy lifting:
213
-
214
-
```java
215
-
// Create a POJO with getters and setters
216
-
publicclassUser {
217
-
privateString name;
218
-
privateString email;
219
-
// Copilot will suggest getter/setter methods
220
-
}
221
-
```
222
-
223
-
### Use Case 2: Algorithm Implementation
224
-
225
-
Ask Copilot to implement algorithms:
226
-
227
-
```python
228
-
# Implement bubble sort algorithm
229
-
def bubble_sort(arr):
230
-
# Copilot suggests the complete implementation
231
-
```
155
+
1. Highlight the function
156
+
2. Open Copilot Chat and ask: "Refactor this function to be more readable and efficient"
157
+
3. Copilot suggests improvements
158
+
4. Apply the changes
232
