  • c-x c-f "autocompletion for file names

A very nice trick with autocompletion is to press c-n c-p to havee a real-time filtering list an works with any kind of autocompletion. This is very useful when we have a lot of suggestions, e.g., like 20 or more suggestions and we may be confused with all that text, so in this case we can just press c-n c-p and type some text to filter.

For example, let's say we want to filter on some filename and we are currently in a directory with a lot of files, we can do: c-x c-f c-n c-p and this will allow us to keep the list and type some text in order to have a better filter.
