I use autocomplete a lot in the terminal, like for example for cp command. But sometimes, when I am putting in the directory for the cp command and I press Tab, the list of files is so long that Ubuntu spits out part of the list and then waits for key input before sequentially listing the rest of the files, one by one. This feature is near useless because you never know how many files are left, and almost always end up with an error.

Is there some way to leave this list and go back to my cp command, or do I have to press Ctrl+C and start typing in my cp command again?
