# A curated list of those Vim How-Tos we search frequently in our daily coding

Vim has been my editor for day to day work for a while, and often times I find myself questing same vim How-To on stackoverflow and websites as such. To help manage a list of my frequent used Vim tips/commands, and potentially be useful to you, I am curating this list of vim How-Tos.

• visual selection in vim ?
Ctl-v - visual block. v - select chars. V - select current line.

• Shortcuts to move cursor in vim ?
gg - to move to start of file. G - to move to end of file. '' - to move to last active point. 0 - to move to start of current line. \$ - to move to end of current line.

• How to run command within vim ?
Syntax: :%![cmd]:
Here % represent that we pass in whole buffer of vim into command for filtering. We can also specify a range instead of passing the whole buffer. For example: :2,5![cmd], :1,100![cmd] A list of examples of running commands within vim:
# Do word count.
:%!wc

#


For buffer to be used, when a visual selection is active, that will automatically be used as buffer input.

For reference:

• %!: pass current buffer.
• 4,!: line 4 through end of file.
• How to beautify ugly json within vim?
With command python -m json.tool:
:%!python -m json.tool


This trys to beautify the whole file.
If there is a need to only beautify a range of lines, use following instead:

:[start],[end]!python -m json.tool


To make it even more convenient for your daily work, nmap this command to some short cut.
Following nmap maps the first command to =j shortcut:

nmap =j :%!python -m json.tool<CR>

• How to search within visually selected text in vim ?
For many reasons/occasions, we need to search within a scope, for example within visually selected text in vim. A simple way:

1. Visually select text. (With v, V or Control-V)
2. Press ‘:’ (colon)

Now you should see prompt as :'<,'>

3. Following that, type in seach or seach replace command, then the search/search and replace will only apply within the selected scope

Demo:
Say you have a list in python and you forgot to quote items, and you can take advantage of this vim tip instead of adding quotes for each of them mannually.

• How to cancel search hilight ?
There are times when you have unwanted search highlight, and you simplely want to cancel the highlight. :noh command exactly do the trick:

1. Simply type : (colon) and follow with noh
