Thanks @iporsut for triggered my curiosity

[VIM] Move screen before cursor reaching top or bottom

It's interesting that I didn't realize I had been living without this feature for years as a vim user. Thanks to @tenderlove and @searls for publishing their vim setup session video. In the beginning of this video, @tenderlove adds set scrolloff=2 to vimrc. scrolloff is a good config that everyone who's using vim should have in their vimrc.

What it does is to tell vim to move screen before cursor reaching 2 top or bottom lines (2 is an arbitrary number). Give it a try. I bet you'll like it.

I went observe on JetBrains' IDE, they are configured to behave the same with setting scrolloff=1 on vim.

[Fixed][VIM] E354: Invalid register name: '*'

This error occurs when you or some of your vim plugins try to access register '*' which is a system clipboard. In default Mac OSX vim, it is compiled without system clipboard support enable. You can check this by run command :version inside vim. In the result, you will see -clipboard. Disable is -, enable is +.

To solve this issue, you need to compile vim with +clipboard yourself. I suggest OSX users to use brew to help this process. Out-of-the-box brew compiles vim with +clipboard. To do this run

brew install vim

Then you might need to create a new symbolic link from your vi command to point to the newly installed vim.
First you need to know the path of your new vim. Run

brew info vim

You should see something similar to /usr/local/Cellar/vim/7.3.875 in the result which means your vim binary file is at /usr/local/Cellar/vim/7.3.875/bin/vim. To create a new symbolic link for vi, first you need to remove the existing link

sudo rm /usr/bin/vi

Then you can create a new link.

sudo ln -s /usr/local/Cellar/vim/7.3.875/bin/vim /usr/bin/vi

[VIM] + and * register don't work with clipboard on MacOSX

This problem is because VIM version that shipped with MacOSX doesn't enable xterm_clipboard. You can check this by run :version command in VIM. Enabled xterm_clipboard VIM must have +xterm_clipboard but the version shipped with MacOSX has -xterm_clipboard.
If you want it to be enabled, you need to compile VIM yourself with clipboard enabling flag.

[VIM] Make newly created file(s) available for search with FuzzyFinder

Once your FuzzyFinder has loaded current files, if you create a new file, you have to tell it to reload it by execute:-

:FufRenewCache

More advance commands for moving cursor and screen in VI

These are VI commands I have just learned today

F = reverse of f
t = f and step back 1 char
T = reverse of t
; = repeat f, F, t and T

H = Move cursor to first line of the screen

L = Move cursor to last line of the screen

z. || zz = Move screen to make cursor to middle of the screen
zt = Move screen to make cursor to top of the screen

Ctrl+f = Scroll down 1 screen (Ctrl+d only half screen)
Ctrl+b = reverse of Ctrl+f

Ctrl+e = Move screen down 1 line with the cursor try to stay at the sameline
Ctrl+y = reverse of Ctrl+y
