Reduce the number of keystrokes it takes to open a file in vim. First of all, you just need to type "v", which is less than half the number of characters (!), and second-of-all, you only need to enter a substring of the file you want to open. For example, if you want to open the file, homework.txt, then type "v hom" to open it. Good tip is to use the lowest unique substring, otherwise you'll open multiple files in different buffers (which is sometimes desirable). Use Ctrl-^ to switch between buffers.

Info has some of the worst keybindings I've ever seen. Being a vim user, I attribute that to emacs influence. Use the --vi-keys option to use some of the vi keybindings, although this won't change all the keybindings. Use the "infokey" program to have more control over info keybindings.

Very handy to bring the word currently under the cursor into a :s command in Vim.

Example:

If the cursor was on the word "eggs":

:s/ ==> :s/eggs

the middle command between the ; and ; is the vi commands that insert that line into the last line of the file, the esc with the carets is literally hitting the escape key, you have to have the smbfs package installed to do it, I use it to access my iTunes music on my mac from my linux PC's with amarok so I can play the music anywhere in the house. among other things, it allows you to access the files on that share from your computer anytime you're on that network.

Within vi allow to empty a text file in one shot

The -R flag prevents you from making changes to a file, useful when you only want to view the file. This command is nicer than the 'more' or 'less' commands because for source codes, vi shows syntax highlight.

This command delete all the empty lines (include the lines with space) from a file.

g = global command

\S = non-whitespace character; !\S the opposite

d = delete a range

On command mode in Vim you can save parts of the current buffer in another file.

* The 'n' value represents the first line of the new file.

* The 'm' value represents the last line of the new file.

* newfile.txt is the newfile.

The results are similar to this command in perl:

Replace all ocurrences in the file.

The g option is to replace more than one occurrence in the same line. Whitout the g option, it only replace the first occurrence in the line.

Edit the files, each in a separate tab. use gT and gt to move to the left- and right-tab, respectively. to add another tab while editing, type ':tabe filename'

Creates a full snapshot of your current vim session, including tabs, open buffers, cursor positions, everything. Can be resumed with vim -S . Useful for those times when you HAVE to close vim, but you don't want to lose all your hard-opened buffers and windows. The ! will cause vim to overwrite the file if it already exists. It is not necessary, but useful if you frequently save to the same file (like session.vim or something).

You can then switch from a file to another with ^W^W

This will append the output of "command" to whatever file you're currently editing in vim. Who else has good vim tricks? :)

The hyphen tells vim to open from STDOUT - saves having to create temporary files.
