Random :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

When in visual mode, "O" and "o" both switch between the starting and ending of the code selected.

When inside a closed block of text (i.e, content between "" or '' or () or {} or [] or <>, etc);

# "i" in visual mode selects text until the outer covering character
# EG: vi" in the text: ""mohit makwana"" : with cursor@t selects: mohit makwana
# EG: 2vi" or va" in the same above case elects: "mohit makwana"
# EG: 2va" in the same above case selects: ""mohit makwana""

Change filelocal in buffer (use case: use vimwiki in any md file):

:bufdo setlocal filetype=vimwiki

Also use substitution more frequently:

# In 1 line in 1st occurence:                  :s/old/new
# In 1 line for all occurences:                :s/old/new/g
# Change every occurences between 2 line no.s: :#,#s/old/new/g
# Change every occurence in whole file:        :%s/old/new/g
# Same as above + prompt asking for each:      :%s/old/new/gc

Also use foll more frequently:

# "C" is equivalent of D + i
# "I" starts insert mode at the beginning of line.
# "R" is replace mode for continuous typing.
# "Y" copies everything from cursor till end of line.
# "y" works similarly like dw/cw with other moving keys like h.j.k.l.w.e..etc.

Insert mode bindings ::::::::::::::::::::::::::::::::::::::::::::::::::::::::

CTRL + U deletes all entered characters in a line. CTRL + W deletes the previous word. CTRL + H deletes the previous character, but honesty its no better than the backspace. CTRL + R inserts contents of register. CTRL + K print keybinding format of what you type. CTRL + E/Y copies and prints characters just below and above the cursor while in insert mode. CTRL + N/P Iterates through cmp suggestions to provide word completion while in insert mode.

END :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

Vim Fold bindings :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

zf#j creates a fold from the cursor down # lines. zf/string creates a fold from the cursor to string. zj moves the cursor to the next fold. zk moves the cursor to the previous fold. zo opens a fold at the cursor. zO opens all folds at the cursor. zm increases the foldlevel by one. zM closes all open folds. zr decreases the foldlevel by one. zR decreases the foldlevel to zero — all folds will be open. zd deletes the fold at the cursor. zE deletes all folds. [z move to start of open fold. ]z move to end of open fold.

Others ::

USEFUL GIT TIP ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

configure: git config --global diff.tool vimdiff git config --global difftool.path nvim git config --global merge.tool vimdiff git config --global mergetool.path nvim use: git difftool branch1:path/to/file branch2:path/to/file

END :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

MACROS ! ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

use 15@w to repeat the macro at 'w' 15 times (use more often!) use @@ to repeat the last macro use @: to repeat the last ex command

END :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

Youtube :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

Here in youtube I use the controls: F/f to full screen <> to increase and decrease speed. M to mute.

If I want to go to full screen the best possibility is disable F. But if I want to mute I need to hit 'im' but in fullscreen I get stuck in insert mode with the message at bottom left. It would be nice a feature to exit insert mode without hitting or <C-[>. Maybe an imap.

It would be also nice to have a key to use when I want to inject javascript. Like: document.getElementsByTagName("video")[0].playbackRate=3; To increase video speed.
