Copilot Basics

Use comments as instruction to auto generate next functions
Use Tab to use autogenerated Text
Use separate chat window to use copilot as regular chat bot or understand existing code
If you want to work with specific part of code, always select that code first before writing any prompt
Try to keep your task simple
the more code copiot write at once, the more chance of hallucinations
Simple trick is use simple keyword in your task description
Also breakdown your main task in to multiple smaller task
Working with multiple files/class/modules
If you're writing code which also depend on different or class then try to keep all related files open in separate tabs
By default copilot don't know which files are relevent to your task
Use @workspace agent so copilot can look into active project files and give suggestions specific to that
Use Slash commands during prompt
Fix To solve error
Explain option to figure out issue
doc to generate documentation
optimize to improve running code time or reduce line of code without changing it's final output

CTRL + I to use inline Chat, this is good option to generate new code or modify existing code
CTRL + Enter to view alternative suggestion in separate chat window
