 **Don't be greedy and set it to the root of your hard drive.
 This will slow vim down way too much because there are just too many files and folders!**
 
+## IDE like features without plugins
 
+We already have syntax highlighting via the `set syntax=on` feature but we can also have autocomplete for quite a lot of scripting languages out of the box.
+This is one of the main reasons we install vim-nox and not vim!
+The shortcut to achieve it is a double whammy `<c-x><c-o>` which triggers omnicomplete.
+Have a look at `:help omnifunc` to learn more about it but first, a hands on example.
+
+1. Open the python file we made before with `vim -u ~/vimrc_basic ~/python_test.py`
+2. Navigate to the end of the file, go into **insert** mode and type `datetime.`
+3. Remain in insert mode after the `.` and hit `<c-x><c-o>`
+4. Stay calm and read on.

+![autocomplete](./assets/vim_02.png)
+
+The screenshot above is probably very much like what you're confronted with.
+The *dropdown* menu is a context aware autocomplete menu meaning these are all functions, methods, classes or variables belonging to this module.
+The horizontal split window at the top shows the documentation of the menu item you have selected. 
+You can navigate this list either with the *arrows* or with `<c-n>` to go down and `<c-p>` to go up.
+
+I personally don't like the documentation jumping up and down on my screen so you can add the following to remove it all together.
+Now to be able to view the documentation we'll need to install some plugins.
+I have not found a clean way of hiding the preview window *and* adding a shortcut to show documentation.
+
+```
+set completeopt-=preview
+```
+
+### Complete more things
+
+Vim can do a lot more than just complete python code.
+When you press `<c-x>` you'll see a menu at the bottom along these lines.
+
+```
+-- ^X mode (^]^D^E^F^I^K^L^N^O^Ps^U^V^Y)
+```
+
+Every `^CHARACTER` is a different mode of autocomplete!
+Try out the `^K` one just for fun.
+It will probably say this the following.
+
+```
+'dictionary' option is empty
+```
+
+We can *set* a dictionary, which is just a list of words, to autocomplete from.
+Let me walk you through an example.
+
+1. Open up a blank text file with my basic vimrc.
+2. Go into **insert** mode and type in `hipp`.
+3. Stay in **insert** mode and type `<c-x><c-k>` which will show the same error message as before.
+4. Exit insert mode with `ESC`
+5. Set the dictionary by typing `:set dictionary=/usr/share/dict/american-english` (you should have this file)
+6. Go into **insert** moder after `hipp` and type `<c-x><c-k>` again.
+
+Nice no?
