Practical Vim Notes 1

1. use . to repeat last change made. 
2. f{char} find the next {char} in this line
3. ; repeat last find command. f, t , etc.
4. perform substitution  repeat by & and reverse by u  (very useful, tip 4)
5. cw cut the word
6. the ideal: one keystroke to move, another one to execute
7. use -u to load vim with the vim script. -u None for none
8. Pressing db deletes from the cursor’s starting position to the beginning of the
9. word
10. daw, delete the whole word.
11. {num}<C-a> add first int num. <C-x> reduce first int num
12. gu, gU upper case or normal
13. ap stand for all paragraph
14. <C-o> repeat last jump
15. : normal {normal actions:  like A ;}
16. @: repeat last EX command than we can use @@
17. While <C-r><C-w> gets the word under the cursor, we can instead use <C-r><C-a>
    if we want to get the WORD at command mode.
18. In addition to the <Up> and <Down> keys, we can also use the <C-p> and <C-n> chords to go backward and forward through our command history. 
19.  Press q: and meet the command-line
20. use ! to run cmd and filter.
