u

CTRL + R
Redo last change (undo the last undo... kinda...)
Deleting
d
Deletes the selected text (also the same as "cut", as in you can paste the deleted text)
de
does the same thing as diw, however, you can delete every next word by pressing the period key ( . )
dd
delete the entire current line
diw
delete the current word
di"
delete the text between the quotes
Cut, Copy, and Paste
y
Copies (yanks) the selected text.
yy
Copies the whole line

P
Paste before the cursor
p

Substitution
:s substitutes
Example:
:%s/something/something_else/g
This finds the word “something” and replaces it with “something_else” in the entire document.
:s/something/something_else/g
Does the same thing, but for only the current line
:%s/something/something_else/gc
Does the same thing as the first example, but asks for confirmation (that's what the “c” is there for.)
