It is very nice if you want to quickly edit a document or file but Pico does not manage large editing jobs as nicely as other editors. ITD at the Univeristy has a Qucik Note Guide to getting started with Pico at Using the Unix Text Editor Pico . For those who wish a more powerful editor, Vi and Emacs provide additional utility. Once you learn VI it can do lots of editing tasks. It is an editor with a command mode and an insert mode.
Command mode is used to move through the text.
The insert mode is for inserting text into a file. You move back and forth between modes as you edit. Many of the students at the University of Michigan who have learned a UNIX editor have learned Vi. For more information see Stephanie Wolf's Unix, vi and X- Windows Guide Emacs is an editor created as a part of the GNU project and made available through the Free Software Foundation. Commands are assigned to special keys.
