22 Sep 09 Using Templates in Vim
I just discovered a way to use templates in Vim where when I create a file, depending on the extension of the file, the boilerplate text that should always be there will be there.
You can find out how to do this from the Vim Recipe book, in particular this page: http://vim.runpaint.org/typing/using-templates/

09 Sep 09 Tips on Using VI Editor (cont’d)
The most attractive feature that VI has to offer is the block visual mode. It is amazingly powerful, especially for those who do coding. With it you can add characters to or remove characters a block of text in a column fashion. For example, you can add characters to a block of text (Figure 1) instantly (Figure 2).

Of course, with power comes complexity. It’s something meant for users whose keyboard (shortcut) dexterity surpasses that of the mouse.

Some of the commands that you use for every session can be placed in a file named “.vimrc” in your home folder.
Personally, when editing code, I like to have my tabs to be of 4 characters wide. I also want the tab characters to be changed to 4 spaces. So in my .vimrc file, I place the following lines:
set smartindent set tabstop=4 set shiftwidth=4 set expandtab
I can then code and have the next line auto-indented. (There is another option called autoindent but it is not as good as smartindent.)
With the options set, the lines can also be indented in command mode or visual mode with the characters >> (shift dot key twice) and un-indented with << (shift comma key twice).

02 Sep 09 Tips on Using VI Editor
This is a one of many mini-posts that I will do on using the VI editor. I’ve recently bumped into some pages that contains valuable information on how to use VI. The problem with it is its too wordy and that makes it hard to look for information when you need it.
So this post and the following ones will use tags relevant to the subject to help the search for relevant information quicker.
D – delete the characters of the line after the cursor position
C – delete the characters of the line after the cursor position and change to insert mode
R – change to insert & overwrite mode; it’s like pressing the Ins key on the keyboard; whereas ‘r’ replaces a single character, ‘R’ replaces every character that you type over
s – behaves like ‘x’ but switches to insert mode
S – deletes the whole line and change to insert mode
