# week four turn out to be one of the best week so far for us**

On week 4, I learnt a little further that Vim operates in four different modes, each serving its unique purpose.

The command line mode: This is for saving, quitting and running commands (: to enter)

The normal mode : This is the default mode when you open vim. It is used for navigating and executing commands.

The insert mode: This is used for editing and typing text

The visual mode : This is for selecting text ( ctrl +v to enter this mode)

New commands were though apart from our regular:
* W: write and
* q: quit

A lot was then introduced
dd - to delete (cut) the current line

:bp - to go back to the previous
:bn - to move to the next file.
:spilt - used to spilt files in the vim editor horizontally
:vsp or :vspilt - this is used to split files in the vim editor verticall
ctrl ww - for switching to the different opened buffers

y - yank (copy) the current line
p - to paste below the current line
u - to undo the last change
Ctrl + r - redo the undone change

On Wednesday we began an introductory class into Python.
