Operating Mode
The simplicity of the Line Mode Browser had several limitations. The Line Mode Browser was designed to work on any operating system using what were called "dumb" terminals. The user interface had to be as simple as possible. The user began with a command-line interface specifying a Uniform Resource Locator (URL). The requested web page was then printed line by line on the screen, like a teleprinter. Websites were displayed using the first versions of HTML. Formatting was achieved with capitalization, indentation, and new lines. Header elements were capitalized, centered and separated from the normal text by empty lines.
Navigation was not controlled by a pointing device such as a mouse or arrow keys, but by text commands typed into the program. Numbers in brackets are displayed for each link; links are opened by typing the corresponding number into the program. This led one journalist of the time to write: "The Web is a way of finding information by typing numbers." The page scrolled down when an empty command (carriage return) was entered, and scrolled up with the command "u". The command "b" navigated backwards in history, and new pages were navigated with "g http://..." (for go to) and the URL.
The browser had no authoring functions, so pages could only be read and not edited. This was considered to be unfortunate by Robert Cailliau, one of the developers:
"I think in retrospect the biggest mistake made in the whole project was the public release of the Line-Mode Browser. It gave the Internet hackers immediate access, but only from the point of view of the passive browser — no editing capabilities"

Famous quotes containing the words operating and/or mode:
“I love meetings with suits. I live for meetings with suits. I love them because I know they had a really boring week and I walk in there with my orange velvet leggings and drop popcorn in my cleavage and then fish it out and eat it. I like that. I know I’m entertaining them and I know that they know. Obviously, the best meetings are with suits that are intelligent, because then things are operating on a whole other level.”
—Madonna [Madonna Louise Ciccione] (b. 1959)
“The mode of clearing and planting is to fell the trees, and burn once what will burn, then cut them up into suitable lengths, roll into heaps, and burn again; then, with a hoe, plant potatoes where you can come at the ground between the stumps and charred logs; for a first crop the ashes suffice for manure, and no hoeing being necessary the first year. In the fall, cut, roll, and burn again, and so on, till the land is cleared; and soon it is ready for grain, and to be laid down.”
—Henry David Thoreau (1817–1862)
