A guy I work with told me about a function that an old IBM text editor had that he said was useful, and that is to create folds in the file after a search such that every line that is visible contains the search pattern(except possibly the first). All lines that do not contain the search pattern are folded up to the last occurence of the pattern or the top of the file.  One use for such a function is to be able to make a quick and dirty api of a source file.  For example, if working in Java, you could run the function using the pattern "public|protected|private" and ithe results would be that only the method headers would be visible (well, close enough).  

With the following, you can use g/ (or g?) to search forwards (or backwards) for the currently selected text.

In visual mode, / and ? will update the visual selection just like any other cursor-movement command. In order to actually search within the visual selection, you will need to use the \%V atom, or use the markers defined by the visual selection with \%>'< and \%<'> atoms. This is best done by leaving the visual selection with <esc> before entering your search. You may want to consider a mapping to automatically leave visual selection and enter the appropriate atom(s). For example:

Nevertheless, spawning a shell in a VIM window is something I desperately sought after since the first day I started working with VIM, and searching on Google reveals that I'm not the only person. Someone even hacked together a Python script so you can start a shell in a window, but it's no terminal emulator, so your possibilities with this "shell" are limited. I wanted to have a real, working shell in VIM, so I wouldn't have to switch around with screen, use half-hearty solutions like splitvt etc.

The grep plugin integrates the grep, fgrep, egrep, and agrep tools with Vim and allows you to search for a pattern in one or more files and jump to them. To use this plugin, you need the grep, fgrep, egrep, agrep, find and xargs utilities. These tools are present in most of the Unix installations. For MS-Windows systems, you can download the GNU grep and find utilities from the following sites:

Cursor line and more... * You can turn on cursor line and cursor columns ':set cursorline' ':set cursorcolumn'

* Pressing 'q:' or ':<Ctrl-f>' gives the command history window (list of previously executed commands in the current session) * Pressing 'q/' or '/<Ctrl-f>' gives the command history window (list of previously executed commands in the current session)

Note: to highlight special keywords we can use the match option as ':hi <MyGroup> ctermbg=red' ':mat <MyGroup> /<pattern>/' To clear these highlights do ':mat[ch]'
