Vim modality

vim has 3 main modes:

Normal mode: For navigation and manipulation of text. This is the mode that vim will usually start in
Insert (edit) mode: For inserting new text, where you type into your file like other editors.
Command mode: For executing extra commands like the help, shell, ...

		            k
		            ^
0 / ^ / B / b / h <   > l / e / E / w / W / $
                    v
                    +
                    j

these commands take you in Insert Mode:

i: insert at left of cursor

o: insert by adding new line below the cursor
O: insert by insert new line above the cursor

paste:

p: paste to the next line

[operator]i[motion]

operators:
