Well :h motion.txt should be your first try. Most imoprtant keys:
hjkl - as experienced user you'll notice that you don't use them that often.
So you should at least know about the following and have a look at :h motion.txt
and create your own by mappings
how to reach insert mode:
| is cursor location
O
I i|a A
o
important movements and their relation:
gg
<c-u> H (top line window)
- k
0 h | l $ M
<cr> j
<c-v>
L
G
N G or :N : goto line number N
movements:
use search / ? to place cursor. Remember that typing a word is not always the
most efficient way. Eg try /ys t this. And you'll get excatly
one match in the whole document.
c-o c-i : jump list history
g; : where did I edit last (current buffer) - you can repeat it
Learn about w vs W. Try it CURSOR_HERE.then.type.it (same for e,E)
f,F,t,T : move to char or just before it forward / backward current line. (A
must), the two keys ; and , repeats that movement in both directions
be faster: delete then goto insert mode:
C: deletes till end of line
c a-movement-action: deletes characters visited while moving
more movements:
(, ): move by sentence
, , {, } : more blockwise movements which are often helpful
...
Of course you can define your own movements easily, such as the well known <c-e>:
inoremap <c-e> <esc>A
However a lot of additional needs and solutions are there.
