If you are new to Vim or you have accidentally opened this editor where you type and nothing happens and you are stuck in this plain maze and don't know how to exit?
To exit you such press :q and hit enter. Nothing happened and you are in still in Vim then press escape and then type :q
Now that you know how to exit. Let's dig in more, there are two modes in Vim.
Insert mode : Press i for insert mode. Where you can just type like a normal text editor.
Command mode : Press ESC for command mode. Where you give commands to the editor to get things done. You can see below left-hand corner of the screen what you are typing.
x – to delete the unwanted character
u – to undo the last the command and U to undo the whole line
CTRL-R - to redo
A – to append text at the end
:wq – to save and exit
:q! – to trash all changes
dw – move the cursor to the beginning of the word to delete that word
2w – to move the cursor two words forward.
3e – to move the cursor to the end of the third word forward.
0 (zero) to move to the start of the line.
d2w – which deletes 2 words .. number can be changed for deleting the number of consecutive words like d3w

The format for a change command is: operator [number] motion
