Keystrokes

Vanilla VIM

Basic actions: {y_ank,c_hange,d_elete, v_{isual selection}}{i_nner,a_ll}{w_ord,t_ag,p_aragraph}

1. m_ark items in order to return to them later - simply hit m and then letter and then it's possible to go back to this place with *** backticks + letter ***

2. use ctrl+a_dd and ctrl+x_tract to increase/decrease counters in your text.

3. go to the latest position with `` (two backticks)

4. repeating last command with . and macros!

   • start recording with q<register_letter>. Invoke with @<register_letter>. @@ invokes the latest macro
   • hit (ctrl + r_egister) + = in insert mode in order to enter an expression mode.
   • write an expression, you can include your yanked content with (ctrl + r_egister) + ". Useful when you need to increment or operate on some kind of a variable within the macro.

5. g~/gU/gu to toggle/upper/lower the case - there's no mnemonic for that :<

6. Use f_ind to find a character in current line

7. Move your cursor to the top, mid and bottom of the screen with respectively H_igh, M_iddle, L_ow keys in normal mode

8. Yank something to register with simply "y something and then paste with "p

   • awesome shortcut - when in INSERT mode just hit ctrl + r and to simply paste register's value, use ctrl + a to paste the last one. Default register is "

9. Use completion modes. Hit ctrl + x_pand and then:

   • ctrl + l_ine to complete whole lines for file
   • ctrl + p_revious to complete words found backwards in file
   • ctrl + f_ilenames to complete filenames
   • ctrl + o_{mnicompletion} for omnicompletion
   • abc</ and then omnicompletion will close html tag
   • ctrl + n_ext for keywords in current file

10. za/zc_lose/zo_pen to toggle/close/open folding

11. In order to change all existing tab characters to match settings, run :retab

12. To unwrap something, e.g. ([{foo: bar}]) -> {foo: bar} just do:

    • ya} to yank content of inner braces (inclusive)
    • va( to select everything in () (inclusive)
    • p to replace selected content with the yanked one

13. Replacement has some super features:

    • :%s//abc will replace all occurences of your last search. Search with /def and then run /%s//abc to replace all def's with abc's
    • use g_lobal flag to replace all in file occurences
    • use c_onfirm flag to confirm every replacement
    • :%s/<foo>/bar/gc wrap words in <> in order to search for full words onyl

14. Use ctrl + o(ut)/ctrl + i(n) to go to previous/next file

15. g_ov_isual in the visual mode returns to the latest selection

16. ctrl + f_orwards/b_ackwards to move backward/forward a page; ctrl + u_p/d_own to go up/down half a page. ctrl + e/y to move without moving a cursor

17. zz/zt_op/zb_ottom to move screen and place cursor's position at center/top/bottom

18. You can escape insert mode with ctrl + c as well.

19. X_tract in normal mode to remove character backwards.

20. g_oi_nsert puts you in insert mode in the last position you were while in insert mode.

21. use :split and :vsplit commands to split the screen horizontally/vertically

22. when you start editing multiple files with vim with e.g. vim a.txt b.txt you can navigate between them with [a/]a keys

23. Use J_oin to join the current line with line below

My additions

1. Glastmsg command - run this command while commiting to paste the last msg inside the text. Useful when you want to reuse some piece of information from the previous commit message (jira ticket number for instance)
2. <leader>ss to remove redundant trailing spaces all over the document
3. <Leader>lx to lint xml
4. <Leader>sh to split horizontally, <Leader>sv to split vertically

With plugins included in my configuration

1. nerdtree -
   • ctrl + n_erdtree to toggle nerdtree
   • <leader>s_howf_ile to show the current file (node in NerdTree)
   • inside the nerdtree hit m_enu to show menu, where you can create a file or something
2. ctrlp - simply hit ctrl + p to search through current file's repository
   • ctrl + d to enter filename-only search
   • ctrl + t_ab to open a selection in a new tab
   • ctrl + x or v to open a selection in a new split
3. fugitive:
   • Gblame - git blame. Hit o when blaming to see the full commit info
   • Glog - loads all previous version of the file - cprev/cnext/cfirst/clast commands allow you to move between version freely
   • Gedit SHA -
   • Gstatus - git status in good looking
4. vim-surround:
   • ysw" for example wraps current word with ""
   • cs"' from inner quote to change surrounding from " to '
   • cst<xyz> replaces current surrounding tag with new <xyz>
   • S<tag> from visual mode to wrap selected items in
5. nerdcommenter:
   • <leader>c<space> to toggle the comment
6. ack.vim:
   • :Ack <phrase> <dir> - dir defaults to current if absent
   • t - open in new tab
7. tabularize.vim
   • :Tab /= to use a column layout with = as a separator

Useless yet interesting hacks

• you can write only specific files. Just enter :15,19 w to write lines 15,16,17,18,19 only.

General bash tips

Movement

• ctrl + a/ctrl + e - beginning/end of the line
• ctrl + k - delete to the end of the line
• ctrl + r/ctrl + s - search backward/forward
• ctrl + w - delete the word behind the cursor

Useful commands

• use !$ to reuse last word of the last command.
• use !! to reuse last command
• ~-/~+ + TAB to show the list of recently entered dirs

Tools

• pipe your file to less if it's too big to fit on screen. Use head or tail (or even tail -f to follow the end of the file) to see the specific part of the file
• wc to count lines, words or characters. Useful if you want to pipe things into wc in order to e.g. find the number of matching files from find
• grep allows you to search a string inside the files. -r for recursive search.
• use ssh-copy-id to copy your identity file to a remote host.

Zsh

Installation

1. git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting
2. git clone https://github.com/peterhurford/git-it-on.zsh ~/.oh-my-zsh/custom/plugins/git-it-on
3. pip install pygments #to make colorize plugin work
4. git clone https://github.com/wting/autojump.git && cd autojump && chmod +x install.py && python install.py

Usage

1. bd - move up in the pwd
2. gitit - open current repo's github
3. colorize <file> | less to get colorized file output
4. autojump - allows to quickly search through visited (at least once) directories. Just type j <partial_filename> to see list of possible files/dirs
5. wd adds tags to directory so after wd add <dir_name> in some directory you can do wd <dir_name> to immediately jump to this dir MORE?
6. take to create a directory and change to it

tmux

• All hotkeys visible via ctrl + ?
• Ctrl+b is a prefix on a host machine
• Ctrl+j is a prefix on a remote machine
• Most useful ones:
• • n/p go to to next/previous window
• • <number> to go to specified window
• • attach/detach
• • c to create a window
• • } to swap windows
• • <right>/<left> to move between panes
• • % / " to split windows with panes - horizontally/vertically
• • $ to rename session
• • z to fullscreen pane

In order to use a config, e.g. for rpi:

1. scp ~/.rpi.tmux.conf pi@raspberrypi:~/.tmux.conf
2. ssh pi@raspberrypi -t tmux -2 a

Tools

• use cloc application in order to reveal the number of lines of code in your project
