h/j/k/l
gg and G – start/end of buffer
^ - first non-blank character in current line
$ - last character on current line
CTRL-u / CTRL-d – page up / page down
:n – go to line number n.
H/M/L – go to first/middle/last line on screen*
% - jump to corresponding bracket [] {} ()](https://image.slidesharecdn.com/vimandpython-120316144521-phpapp01/85/Vim-and-Python-2-320.jpg)
![tags
I map F4 to rebuild tags file using ctags
CTRL-] - jump to tag under cursor
CTRL-T – return to where you came from
:tag <tagname> - jump to a tag
If there are multiple matches, you select from a
list
taglist is another useful plugin to view the tags in
the current file](https://image.slidesharecdn.com/vimandpython-120316144521-phpapp01/85/Vim-and-Python-16-320.jpg)
Vim and Python

- 2. Getting Around h/j/k/l gg and G – start/end of buffer ^ - first non-blank character in current line $ - last character on current line CTRL-u / CTRL-d – page up / page down :n – go to line number n. H/M/L – go to first/middle/last line on screen* % - jump to corresponding bracket [] {} ()
- 3. Marks m followed by a letter to set a mark ` followed by the letter – jump to that mark :marks will list current marks Vim has some special marks (a few examples): `. - jump to position where the last change occured `` - jump back to position where you jumped from lots more found in :help `
- 4. Making Changes y/d/c – yank/delete/change Y/D/C – same as above, but specifies line* p/P – paste before/after combine with movements: dw – delete word cw – change word dG – delete from cursor to end of file c`a – change from cursor to mark a
- 5. Making Changes y/d/c – yank/delete/change Y/D/C – same as above, but specifies line* p/P – paste after/before x/r – delete/replace single character combine with movements: dw – delete word cw – change word dG – delete from cursor to end of file c`a – change from cursor to mark a use the . character to repeat last command
- 6. Visual Mode v – enter visual mode V – enter visual mode, but operate on a line CTRL-v -enter visual mode, operate on a column Use I to change all columns at once combine with y/d/c for even more fun
- 7. Text Objects used after an operator or visual mode i – inner / a – ambient a' / i' – operate on block of '' a( / i( - operate of block of () a{ / i{ - operate of block of {} at / it – operate of html or xml tags
- 8. Search / or ? - for a basic search (forward or backward) I recommend :set ignore case, :set smartcase and :set incsearch n to repeat search, or N to repeat in opposite direction */# - find next/previous of word under cursor [I – list lines with word under cursor set up a map to make this easier: :map <space>f [I:let nr = input("Which one: ")<Bar>exe "normal " . nr ."[t"<CR>
- 9. Undos u – undo, CTRL-R – redo see also: undo-branches time travel :earlier Ns, m, h :later Ns,m,h Can't jump to the future when the code is already done, sorry. Hoping for that feature in Vim 8
- 10. Splitting Windows :sp -horizontal split :vs – vertical split :new CTRL-w + movement to move between windows I remap spacebar for easier commands
- 11. Configuration .vimrc – global settings .vim directory - plugins, color schemes, syntax definitions, etc browse github for ideas, or just fork one you like :set – see your current settings don't be afraid to consult :help to see what things do
- 12. Config Examples filtype plugin on – recoginize .py as python filtype indent on – proper indentation (more on this later) set nu – turn line numbers on set ruler – see where you are in the file set t_Co=256 – 256 colors cmap w!! %!sudo tee > /dev/null % made changes to a read-only file? This mapping allows you to use :w!! to save using sudo
- 13. More Config Examples au BufReadPost * if line("'"") > 0 && line("'"") <= line("$")|execute("normal `"")|endif jumps cursor to last edited position on file open set pastetoggle=<F10> easy way to shift to paste mode to not screw up indentation nmap <silent> <F6> :set number!<CR> turn line numbers on/off set iskeyword-=- use dash as a word seperator
- 14. Indentation My biggest hang-up when I started with python Found a python indent file that works pretty well Found in .vim/after/indent/ Autoindents/unindents around keywords Various other indent definitions available (djangohtml is another I use) = command will re-indent use > and < to indent keys
- 15. Autocomplete <tab> invokes autocomplete Use options wildmode and wildmenu to change how this works (I use list:longest,full) Also work on filenames/directories (:e <tab>) There are other forms of autocomplete: Omnicomplete – Heuristics based completion, I haven't had much luck pydiction plugin – keyword/modules
- 16. tags I map F4 to rebuild tags file using ctags CTRL-] - jump to tag under cursor CTRL-T – return to where you came from :tag <tagname> - jump to a tag If there are multiple matches, you select from a list taglist is another useful plugin to view the tags in the current file
- 17. NERDtree Popular file explorer Opens in a new window, which can be re-sized and customised Supports bookmarks I prefer to just use :e + <tab>
- 18. SelectBuf Similar to a file explorer, but limited to buffers already open A must-have if you normally operate many buffers at once
- 19. flake-8 wrapper for flake8 (must install seperately) PyFlakes PEP8 complexity checker Can configure to ignore errors I map to F5, as I also use makeprg for other languages using the same key
- 20. Doxygen Generate comment skeletons :DoxLic - License :DoxAuth - Author :Dox - function/class block headers Works well out of the box, but config options available
