GENERAL
    to get help type :h <any command>
    like :h ]p
    . can be used to repeat previous command

MAPPINGS
    map is recursive, noremap is non recursive
    map! is only for insert mode

INDENTATION
    >> or << sets the indentation and then . can be used to repeat the direction of indentation
    == also doesn something in vim. automated indentation. Didnt work in python. HTML and js might work. 
    How to set up different shift widths in python. html and js is to be searched. 
    ]p is paste at current level of indentation instead of starting of the line. 
    instead of j if + is used to go down movememnt it straight away takes to first letter of the line. (first non white space letter)

TABS
    to open multiple tabs in vim is -p flag while opening vim
    vim -p afile anotherfile anotheranotherfile
    to open another file from inside vim in a new tab use
    :tabe newfile
    to move to next tab use 'gt' command and 'gT' for previous file
    these both gt and gT are loopable
    to move directly to a tab use 1gt, 2gt ot xgt fot xth tab
    Tabs can be reorganised. :tabm 2 takes the current tab to tab directly after 2nd one. 
    :tabm takes it directly to the last
    

COPYING TEXT
    :-13,-9t. - copy the text between -13 and -9 lines and paste it at current position

SEARCH
    q/ instead of just / opens up search history and search can be chosen from there
    to access search history when you have already started typing the search terms, use ctrl-f 
    to search comments use /".*$, to search for only line comments, ignoring comments after the code in same lin use /^".*$


SEARCH AND REPLACE
    :-13,-9s/orignialtest/replacedtest replaces the words in mentioned lines
    :-13,.s/blah/bluh here . is current position so replace stuff in all lines between -13 and current one..
    :s/u/uu does replace on single line
    :%s/u/uu on whole file
    The serarch term can be a regex
    c flag can be done for confirmation. :s/w/ppp/c
    i flag is for case insensitive search
    g flag means global. all lines and all occurances in a line
    There is gsearch facility for searching across files

DELETE TEXT
    :-13,-12d - deletes the mentioned lines
    da", da{, da( - delte around <delimiter>. this deletes around the text inside the delimiter and delimiter itself

MODIFY TEXT
    :ci<delimiter> ci" will change everything inside the double quotes if you are in a double quote string
        ci{ will change everything inside the curly braces you are in, and similarly ci(
        this also works woth things other than delimiters like, w for word,
        this also works with a instead of i which is around and includes delimiters
    gi would take you to the position where you were in insert mode last time and open insert mode again. 
        this is for people to roam around, checkout stuff and then come back and work


SPLIT
    :windo prefix to any command makes it applied to all opwn splits
    :windo e! reloads all files and removing all unsaved changes
    :windo %s/integer/float/g | w - makes the search and replace across splits and saves all the files
    :only closes all other splits except the current context split
    ,- maximizes the current split to full window 
    ,= restores the original layout by demaximizing the maximized window

MOVE AROUND
    { and } to move between paragraphs
    % to move between matching braces or prenthesis
    gg to start of the file
