Fuzzy Finder FZF with Syntax Highlight Preview

FZF is nice cli program that allow quick file navigation that find files as you type.

BAT is nice replacement for cat with highlight features

Using fzf together with batcat to source code files and preview it with syntax highlight

fzf --preview 'batcat --style=numbers --color=always --line-range :500 {}'

C/C++ manpages quick access from VIM

Vim has by default a helpful shortcut to open the man page of the word under cursor, Shift + k, (or captital K), but very frequently we have shell commands with the same name of a C function, and for example

man printf actually opens the man page for the command, not the C function, but

man 3 printf opens the man pages of the C function, so to open this same man page in Vim, you need to use Shift + 3k (3K)

and for example readlink C function it's man 2 readlink, so in Vim it is Shift + 2k (2K)

Install C++ man pages libstdc++-10-doc
