In computing, a tab is one of two different control characterss in ASCII. A tab key is the part of a keyboard which creates tabs. The most known and common tab is a horizontal tab, which in ASCII has the decimal character code of 9. There is also a vertical tab which in ASCII has decimal character code 11. Tabs are almost always rederened as a form of whitespace while some text editors mark tabs with some special graphics to facilitate distinguising tabs and whitespaces.
A UNIX program, expand expands tabs to spaces and unexpand does vice versa.
Also, in computer programming, the use of tabs for code formatting is an ongoing debate. See Jamie Zawinski's "Tabs versus Spaces: An Eternal Holy War" for further explaination.
