Vim Commands I Use Every Day

You do not need to learn all of Vim. You need about twelve commands.

Navigation

h j k l   — move
w b       — word forward / back
^ $       — start / end of line
gg G      — top / bottom of file
Ctrl-d/u  — page down / up

Editing

x         — delete character
dd        — delete line
yy        — yank (copy) line
p         — paste below
u Ctrl-r  — undo / redo

Insert Modes

i         — insert before cursor
a         — append after cursor
o         — open new line below
I A       — start / end of line

The rest you pick up organically when the need arises. Resist the urge to learn everything at once.
