The below two are particularly useful if you have a very long command.

• Delete everything from the cursor to the end of the line:

Ctrl + k

• Delete everything from the cursor to the start of the line:

Ctrl + u

• Delete one worked backwards from cursor:

Ctrl + w

• Search your history backwards, this is probably the one that I use the most, it is really handy and speeds up my work-flow a lot:

Ctrl + r

• Clear the screen, I use this instead of typing the clear command:

Ctrl + l

• Stops the output to the screen:

Ctrl + s

• Enable the output to the screen in case that previously stopped by Ctrl + s:

Ctrl + q

• Terminate the current command

Ctrl + c

• Throw the current command to background:

Ctrl + z

I use those constantly every day and it saves me a lot of time.
