== jumps ==

"jumps" are movements of the cursor.

== left/down/up/right ==

h   jump one character to the left
j   jump one line down
k   jump one line up
l   jump one character to the right

== BOL/EOL ==

jumps to begin-of-line (BOL) and end-of-line (EOL):
0   jump to "column zero" (begin-of-line)
$   jump to last column

== word vs WORD ==

concept of "word" and "WORD":
word  string of "letters"
WORD  string of non-whitespace

== BOW/EOW ==

jumps to begin-of-WORD and end-of-WORD:
B   jump back    onto previous begin-of-WORD
E   jump forward onto next       end-of-WORD
W   jump forward onto next     begin-of-WORD

== home/middle/last line ==

jumps within the current window:
H   "home"   to first  line within current windows
M   "middle" to middle line within current windows
L   "last"   to last   line within current windows
the cursor will be positioned on the first non-whitespace

== line jumps ==
"line jumps" which only find matches on the current line.

fx  find      next 'x', forward  - and jump onto it
Fx  find      next 'x', backward - and jump onto it
tx  jump unto next 'x', forward  - and jump onto character before it
Tx  jump unto next 'x', backward - and jump onto character before it

== bracket match ==

jumping between matching brackets:
%   jump to the matching 'item' under the cursor
    eg bracket ('()'), square bracket ('[]'), or curly brace ('{}')

= Options =

display partial/uncompleted commands:
:set showcmd

display of special characters:
:set list       turns on "list display/mode"
:set listchars=eol:$,tab:>.,trail:*
  EOLs  with dollar signs
  TABs  starting with '>' and expansion with '.' (dots)
  trail trailing whitespaces with asterisks

:set nu   shows line NUmbers

expansion of current option values:
:set option=<TAB>

changing TABs to spaces (of current tabstop):
:set expandtab
:retab

== Concepts ==

undo+redo:
u       undo last (change) command
        does not undo jumps, only changes.
CTRL-R  redo last undone command

see also: :help redo.txt

concept of number prefix
  9dd   delete nine lines (current line and the next 8 lines)

concept of command combination
  dt)   delete unto the next closing bracket

a combination of both number prefix and command combination:
  d2f,  delete to the second finding of the next comma

= Summary =

you should now know these things:

jumps:
  hjkl
  0 $
  BEW
  HML
  fFtT
  %

concepts:
  number prefix
  command combination
  undo+redo

options:
  expandtab number showcmd list listchars

= Exercises =

play vim-adventures.com :-)

= Q&A =

q: can you apply the fFtT commands to find matches in following lines?
a: no. you have to use '/' and '?' for finding characters/strings then.

q: can you change the meaning of letters and their commands?
a: yes, you can assign other commands (and even command sequences)
   to letters and other characters with the ":map" command.

= Outlook =

more "find jumps" with "/?nN".
more command combinations.
more concepts (filtering, folding, visual modes)
more settings (vimrc etc).
buffers and registers.
session file.
