Hotkeys in Bash helps you use Bash more efficiency. Most of them have slower analogs. But some of them help you easier do common things.
Ctrl + a – Return to the start of the command you’re typing
Ctrl + e – Go to the end of the command you’re typing
Ctrl + u – Cut everything before the cursor to a special clipboard
Ctrl + k – Cut everything after the cursor to a special clipboard
Ctrl + y – Paste from the special clipboard that Ctrl + u and Ctrl + k save their data to
Ctrl + t – Swap the two characters before the cursor (you can actually use this to transport a character from the left to the right, try it!)
Ctrl + w – Delete the word / argument left of the cursor
Ctrl + h – Delete the one symbol left of the cursor
Ctrl + l – Clear the screen
Now you are more efficient in Bash than you were before.
